I do it for the first one I have to do that I need it for me to do not feel like I need it to be honest and help my head
F(x) = 3x
F(7) = 21
g(x) = -x + 1
g(7) = -7 + 1 = -6
(F x g)(7) = (21) (-6) = -126
17/24
Take 1/6 multiply it by 4 and get 4/24
Take 7/8 multiply it by 3 and get 21/24
Subtract 4 from 21
Answer is 17/24
