The y-intercept is (0,a) since y = ab0 = a(1) = a. For example, if the exponential function is y = 3x, the y-intercept is (0,1). Transformations of exponential functionsLet c be a positive real number. There are basically 5 types of transformations that can happen with exponenti...
Answer to: An exponential function f(x) = ab^x passes through the points (0, 8000) and (2, 3920) . what are the values of a and b ? By...
The y-values are being multiplied by the same number each time x increases by a set interval. For example, the y-values might get cut in half each time x increases by 20.How do you graph an exponential function? To graph y = ab^x or y = ab^x + c, first plot (0, a) if ...
How do you write an exponential function?In general, an exponential function is written as f (x) = a bx or as f (x) = a bcx, where a, b, and c are constants.Previously, you have dealt with such functions as f (x) = x2, where the variable x was the base and ...
The value, V, of a car can be modelled using an exponential function V=ab^t, where t is the time in years since the car was purchased and a and b are constants. The car was purchased at the beginning of 2008. The table shows value at the beginning of subsequent years.Show that V...
(-1,4) →f(-1) =ab-1= 4 (1,1) →f(1) =ab1= 1 Solve first equation fora: Plugainto second equation: Equation:f(x)=2•(½)x(you can Check this answer by plugging in the two points.) Example 3:(harder)Find an exponential function of the formf(x)= abxwhich will pass...
If the function y=abx and b>1 , then the function is an exponential growth function. If the function y=abx and 0<b<1 , then the function is an exponential decay function. As noted before, "b" can never be exactly 1. Exponential Growth and Decay Formulas When referring to exponential...
An exponential function's general form is: {eq}f(x) = b^x {/eq} Wherein {eq}x = \text{a variable} {/eq} {eq}b = \text{a constant greater than 0... Learn more about this topic: Exponential Function | Definition, Equation & Examples ...
