Question

Given: f(x)=x+2 and h(x)=1/x-1

Evaluate the following function at x=2.

[h(x)]^2/f(x)

a. 1/4

b. 2

c. 4

Answer 1

First step is to plug in h as 1/x-1 and f as x+2

[h(x)]^2/f(x)

[1/x - 1]² / x + 2

then plug in x as 2 and solve

[1/x - 1]² / x + 2

[1/2 - 1]² / 2 + 2

[-1/2]² / 4

1/4 / 4 convert this into a division problem to solve more easily

1/4 ÷ 4/4 invert the fraction that you are dividing by (4/4) and multiply

1/4 x 4/4

4/16

1/4

The answer is then a.
