Exercise 2 Page 167

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

22

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^2+4

x= 3

f( 3)=2( 3)^2+4

Calculate power

f(3)=2(9)+4

Multiply

f(3)=18+4

Add terms

f(3)=22
