Exercise 16 Page 278

Substitute - 1 for x in each instance of the x-variable.

3/2

Practice makes perfect

Using the function f(x), we want to evaluate for the given value, x=- 1. To do this, we need to substitute - 1 for x in each instance of the x-variable.

f(x)=3(2)^x

Substitute

x= - 1

f( - 1)=3(2)^(- 1)

NegOneExponentToFrac

a^(- 1)=1/a

f(- 1)=3(1/2)

a* 1/b= a/b

f(- 1)=3/2
