Evaluate the following and show steps. f (x) = 15x - 12 and g (x) = - 15x2 + 14x - 10 find g (f (7))

When we have a function such as h (x) = 2x, and we want to find the value of h at a given x value, we plug in the given number for x. For example, h (3) = 2*3 = 6.

We do the same thing with g (f (7)). In this case we plug 7 into f (x) for x, then plug the result of f (7) into g (x) for x.

f (7) = 15*7 - 12 = 93

g (93) = - 15*93^2 + 14*93 - 10 = - 128443
