# Given #f(x) = -3x^2 - 8# and #h(x) = 6x + 2# how do you find f(h(x))?

##### 1 Answer

This means to plug function h in the place of x into f.

#### Explanation:

Note that

When a number replaces the x in parentheses you must plug that number in for x in the inner function, find the result of that calculation, and then plug that in for x in the outer function. When there are three or more functions, make sure to work from the inside out, in the functions' respective order.
