Exercise 11 Page 162

We need to substitute - 2 for x in each instance of the x-variable.

h(- 2)=- 46

Practice makes perfect

To calculate h( - 2) we need to substitute - 2 for x in each instance of the x-variable.

h(x)=- 3x^4+2x^3-12x-6

x= - 2

h( - 2)=- 3( - 2)^4+2( - 2)^3-12( - 2)-6

Calculate power

h(- 2)=- 3(16)+2(- 8)-12(- 2)-6

Multiply

h(- 2)=- 48-16+24-6

Add and subtract terms

h(- 2)=- 46
