For the given functions f and g, find the indicated composition: f(x) = 14x^2 - 10x, g(x) = 7x - 8 (f*g)(9) hint: the answer is 41,800 but i dont know how to show the work for it.

We need to find (fog)(x). Question says composition functions

(fog)(9)= f (g (9))

First we find g(9)

g(9)= 7(9) - 8 = 55

(fog)(9)= f (g (9))

Plug in 55 for g(9)

(fog)(9)= f (g (9)) = f(55)

Now we plug in 55 for x  in f(x)  and find f(55)

so (fog)(9) = 41,800

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
