Exercise 9 Page 278

Is the independent variable x an exponent?

Is it an exponential function? No.
Explanation: Although it fits the pattern y=ab^x, b cannot be negative.

Practice makes perfect

We want to determine whether the given rule represents an exponential function. Notice that even though the independent variable x is an exponent, b cannot be negative. Therefore, the rule does not represent an exponential function.

General Form:& y= a * b^x Given Function:& y= 9 ( - 5)^x
