Exercise 55 Page 491

What is the general form of an exponential function? What does each of the values represent?

3

Practice makes perfect

We want to identify the growth factor b in the given exponential function. To do so, let's first recall the general form of an exponential growth function.

y= a * b^x, where a>0 and b>1 Here, a is the initial amount and the base b is the growth factor. Let's now consider the given function. y= 7 * 3^x We see that a= 7 and b= 3. Therefore, the growth factor is 3.
