TELL WHTHER THE FUNCTION IS EXPONENTIAL GROWTH OR DECAY WORKSHEET

Determine which functions are exponential functions. For those that are not, explain why they are not exponential functions.

Problem 1 :

f(x) = 2^x + 7

Problem 2 :

g(x) = x²

Problem 3 :

h(x) = 1^x

Problem 4 :

f(x) = x^x

Problem 5 :

h(x) = 3 ⋅10^-x

Problem 6 :

f(x) = -3^{x + 1} + 5

Problem 7 :

g(x) = (-3)^{x + 1} + 5

Problem 8 :

h(x) = 2x - 1

Answer Key

2) quadratic function.

3) constant function.

4) it is neither

5) exponential decay function.

6) an exponential decay function.

7) an exponential decay function.

8) It is a linear function.
