Question

Let f(x) = 1/ x-4 and g(x) = 1/x -2, evaluate the following.

a. f( 1/2) =
b. g(1/2)=
c. f (-1/4)=
d. g(-1/4) =

Answer 1

Explanation:

Key : Plug in the numbers given in the parenthesis into the x values of the corresponding functions.

f(1/2) = 1/ 1/2 - 4 = 1/-7/2 = -2/7

g(1/2) = 1/1/2 - 2 = -3/2

f(-1/4) = 1/-1/4-4 = 1/-17/4 = -4/17

g(-1/4) = 1/-1/4 - 2 = 1/-9/2 = -2/9
