Let f(x) =-3x-4 and g(x) =2x-6. find (f×)

a)-20
b)56
c)17
d)28

56

Step-by-step explanation:

(f of g)(x)=f(g(x))

(f of g)(-7)=f(g(-7))

find g(-7) first for easier time

g(-7)=2(-7)-6=-14-6=-20

f(g(-7))=f(-20)

f(-20)=-3(-20)-4=60-4=56

(f of g)(-7)=56

hope this helps

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
