F(x) = -5x
g(x) = 8x^2 - 5x - 9
find (f•g)(x)

B

Step-by-step explanation:

You are making composite functions, since all the answers provided dont fit, I only suggest to clearify that the lone term in the B option, is actually 45x and not 45.

If this is the case, composite functions means that you eval the expresion g(x) in every x variable found in f(x).

Using this, it gives you that f(g(x))=

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
