Answer:

37

Step-by-step explanation:

f(x) = 2x-1

g(x) =x^2 +3

f°g(x) = means put g(x) in for x into the function f(x)

f(g(x)) = 2 (g(x)-1

           =2(x^2 +3) -1

    Distribute

           = 2x^2 +6-1

           =2x^2 +5

Now we let x=-4

f(g(-4)) = 2 (-4)^2 +5

           =2(16) +5

            =32+5

            =37
