Answer:
The answer to this question is -21.
Explanation:
f(g(-3)) says "f at g at -3".
"Evaluating the value of g if x is -3, Then put the value of x into the f function".
g(x) = x - 4
g(-3) = 3x +5
g(-3)=3*(-3)+5
g(-3)=-15+5
g(-3)=-10.
put -10 into the f.
f(x)=2x-1
f(-10)=2*(-10)-1
f(-10)=-20-1
f(-10)=-21.
so f(g(-3))=-21.
