Exercise 18 Page 278

Substitute - 3 for x.

8

Practice makes perfect

To evaluate the given function for x=- 3, we should substitute - 3 for x in the given function and then simplify.

f(x)=0.5^x

x= - 3

f( - 3)=0.5^(- 3)

a = 2* a/2

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

(a/b)^(-n)=(b/a)^n

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

a/1=a

f(- 3)=2^3

Calculate power

f(- 3) = 8
