Question

Given ƒ(x) = − 1 2 x + 7, find x when ƒ(x) = 10. A) −6 B) −3 C) 2 D) 7

Answer 1

Answer: x = -1/4

Step-by-step explanation:

Since f(x) is given as 10 , just substitute into the equation given , that is

10 = -12x + 7

Collecting the like terms , we have

12x = 7 - 10

12x = -3

x = -3/12

x = -1/4
