Exercise 49 Page 82

Substitute - 4 for x to calculate the function's value.

- 46

Practice makes perfect

Using the function g(x), we want to evaluate for the given value, g( - 4). To do this, we need to substitute - 4 for x.

g(x)=- 3x^2+2

x= - 4

g( - 4)=- 3( - 4)^2+2

Calculate power

g(- 4)=- 3(16)+2

Multiply

g(- 4)=- 48+2

Add terms

g(- 4)=- 46
