Exercise 1 Page 167

Substitute - 1 for x to calculate the function's value.

6

Practice makes perfect

Using the function f(x), we want to evaluate for the given value, f( - 1). To do this, we need to substitute - 1 for x.

f(x)=2x^2+4

x= - 1

f( - 1)=2( - 1)^2+4

Calculate power

f(- 1)=2(1)+4

Identity Property of Multiplication

f(- 1)=2+4

Add terms

f(- 1)=6
