Question

If h(x) = 3x − 1 and j(x) = −2x, solve h[j(2)] and select the correct answer below.

-11
11
-13
13

Answer 1

- 13

Explanation:

To evaluate h(j(2)) substitute x = 2 into j(x) then substitute the value obtained into h(x)

j(2) = - 2 × 2 = - 4, then

h(- 4) = (3 × - 4) - 1 = - 12 - 1 = - 13

Hence h(j(2)) = - 13
