Exercise 12 Page 162

We need to substitute - 7 for x in each instance of the x-variable.

f(- 7)=16 193

Practice makes perfect

To calculate f( - 7) we need to substitute - 7 for x in each instance of the x-variable.

f(x)=7x^4-10x^2+14x-26

x= - 7

f( - 7)=7( - 7)^4-10( - 7)^2+14( - 7)-26

Calculate power

f(- 7)=7(2401)-10(49)+14(- 7)-26

Multiply

f(- 7)=16 807‬-490-98-26

Subtract terms

f(- 7)=16 193
