Exercise 5 Page 159

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

f(- 2)=- 90

Practice makes perfect

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

f(x)=3x^5-x^4-6x+10

▼

Evaluate

x= - 2

f( - 2)=3( - 2)^5-( - 2)^4-6( - 2)+10

Calculate power

f(- 2)=3(- 32)-16-6(- 2)+10

Multiply

f(- 2)=- 96-16+12+10

Add and subtract terms

f(- 2)=- 90
