How do you graph an exponential function? To graph y = ab^x or y = ab^x + c, first plot (0, a) if there is no c term, or plot (0, a + c) if there is acterm. Then, draw a dotted line at y = 0 for the asymptote if there is no c term, or draw a dotted line at...
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 number 2 was the power. In the case...
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...
(a) f(x) =e2x − 2, (b) f(x) =e3x +e2x −e2, and (c) f(x)=ex2−1−4. e2x−2,e3x+e2x−e2,ex2−1−4 The figure clearly shows real roots for each function. The next question is, given an exponential function with real roots, how does one find these roots...
The horizontal asymptote of an exponential function f(x) = abx+ c is y = c. Domain and Range of Exponential Function We know that thedomain of a functiony = f(x) is the set of all x-values (inputs) where it can be computed and the range is the set of all y-values (outputs)...

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...
