For the function f(x)=7x+10 and g(x)=-4x-4, find (f * g)(x) and (f * g) (x) and (f * g)(-3)

Step-by-step explanation:

f(x)=7x+19, g(x)=-4x-4

(f*g)(x)= f(g(x))= f(-4x-4)

but f(x)=7x+10

so f*g(x)=7(-4x-4)+10=-28x-28+10

= -28x-18

therefore f*g(-3)= -28(-3)-18 =84-18=66

do i do it on a graph?

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
