Exercise 63 Page 152

Substitute - 3 for x to calculate the function's value.

- 1

Practice makes perfect

Using the function f(x), we want to evaluate for the given value, f( - 3). To do this, we need to substitute - 3 for x.

f(x)=2x+5

x= - 3

f( - 3)=2( - 3)+5

a(- b)=- a * b

f(- 3)=- 2* 3+5

Multiply

f(- 3)=- 6+5

Add terms

f(- 3)=- 1
