Find f o g o h.

Question

f(x) = x + 9, g(x) = 3x, h(x) = x − 5

Answer 1

f(g(h))=[3(x-5)]+9
=3(x-5)=0
=3x-15=0
=3x=15
=x=5
f(g(h))=[5]+9
=14

Answer 2

thanks for trying to help but that is incorrect. The correct answer is 3x-6

Answer 3

g(h) = 3h = 3(x-5) = 3x-15
f(g(h)) = g(h)+9 = 3x-15 + 9 = 3x-6
