Question

Help me with this question i don’t understand what to do

Answer 1

- 36

Explanation:

First evaluate g(18), then substitute the value obtained into h(x), then substitute the value obtained here into f(x).

g(18) =
`√(2(18))` =
`√(36)` = 6, then

h(6) = | 4(6) | - 12 = | 24 | - 12 = 24 - 12 = 12, then

f(12) = - 3(12) = - 36
