Correct answers: 3 question: Consider the exponential function f(x) = 2(3x) and its graph. Exponential smoothing is a rule of thumb technique for smoothing time series data using the exponential window function.Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time. Here, the y-intercept is 1 (x=0). Which two functions have the same initial value? 2. Step-by-step explanation: We need to find the exponential function has an initial value of 2. The domain of an exponential function is all real numbers. 1. Step 3: Solve for the initial value, Well use the function f ( x) = 2 x. The The range of f is all positive real numbers if a > 0. And this is essentially the value of the function when the input is zero. The general form of the exponential function is f(x) = abx, where a is any nonzero number, b is a positive real number not equal to 1. Which exponential function has an initial value of 2 Advertisement cadatheroo is waiting for your help. the initial value of the function is2368.the base of the function is2368.the function shows We are also given the point (3,128). , then a is the initial value. The rate of decay, r = 5% = 0.05 . Solve this by using exponential formulas and round your answer to the nearest two decimals. What is [latex]f\left(3\right)[/latex]? Select all that apply. A. f (x)=2 (3^x) Which function could be a stretch of the exponential decay function shown on the graph? a. f(x) = 2(3x) b. f(x) = 3(2x)Step 2: Simplify the equation in step 1. Source : https://www.gauthmath.com/solution/Which-exponential-function-has To check function which has Which Exponential Function Has an Initial Value of 2 Photo Courtesy: monkeybusinessimages/iStock When y'all get into an auto accident, your automobile isnt the Again, see that 2x3 =(23)2x = (1 8)2x 2 x 3 = ( 2 3) 2 x = ( 1 8) 2 x, so the initial value of the function is 1 8 1 8. Which function has the highest growth rate? 2. Assume that a function has an initial value of \(A = 5\), and when \(x = 4\) we have that \(f(4) = 2\). where a is a non-zero real number called the initial value and b is any positive real number such that b 1. The function f(x) = 2* curves upward from its initial value. Recall the table of values for a function of the form f ( x) = b x whose base is greater than one. Dividing the bottom equation by the top gives n m Pa4 Pa2 a4 a2 = a2. At x < 0, the x-axis becomes the of the graph. 128 = 2(b)3. Which function has the highest growth rate? for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. ANSWER: So, this is the first case of the type of information we can be given. exponential function y=starting value(growth factor)^x growth or decay factor the b value (fixed multiplier) initial value the starting amount or y-intercept of the graph. This nature of the function has x values that are numbers. Observe how the output values in Table 1 For example: Let [latex]f\left(x\right)={2}^{x}[/latex]. Which function has the highest initial value? Here is an example of an exponential function: y= 2x y = 2 x. Which exponential function has an initial value of 2? Now, solve for b. Which functions have positive growth rates? Good Question (90). Remember, there are three basic steps to find the formula of an exponential function with two points: 1. 128 = 2(b)3. Add your answer and earn points. So, for in these cases, the initial value for the function, h, is going to be, h of zero. Steps to Solve Exponential Equations using LogarithmsKeep the exponential expression by itself on one side of the equation.Get the logarithms of both sides of the equation. You can use any bases for logs.Solve for the variable. Keep the answer exact or give decimal approximations. Which exponential function has an initial value of 2? The function f(x) = 2* curves upward from its initial value. Thus a2= n m and so a = n m 1/2 r n m Returning to the equation N(2) = m, we now have P r n m 2 = Pa2= m Using the power law and dividing we get P = m n m m2 n Represented by the The correct option is A) has an initial value of 2 . If neither of the data points have the form \left (0,a\right)\\ (0,a) , substitute both points into two equations with the form f\left (x\right)=a {\left (b\right)}^ {x}\\ f (x) = a(b)x . Question: (4 points) Consider the four exponential functions graphed in the figure below. 3. Using a, substitute the second point into the equation f\left (x\right)=a {\left (b\right)}^ {x}\\ f (x) = a(b)x , and solve for b. Which exponential function has an initial value of 2? rewrite the formula to find voltage. C. f (x)=2 (1/6) Consider the the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. Initial Value of a function itself means the value of function near to zero. Mathematically we can say that Initial Value of function means limiting value of function when time tends to zero. This means, Note that limiting value of f (t) is taken as f (0+) not f (0-). This is because the function is defined t0. To evaluate an exponential function with the form [latex]f\left(x\right)={b}^{x}[/latex], we simply substitute x with the given value, and calculate the resulting power.
