The answer to problem one is the value 96
=============================================
Explanation:
(g o h)(-7) is the same as g(h(-7))
We need to find the value of h(-7)
h(t) = t^2+1
h(-7) = (-7)^2+1 ... replace t with -7
h(-7) = 50
g(h(-7)) turns into g(50) after we replace "h(-7)" with "50"
Now compute g(50)
g(t) = 2t-4
g(50) = 2*50-4
g(50) = 96
So because g(50) is the same as g(h(-7)), this means g(h(-7)) = 96
Since (g o h)(-7) is the same as g(h(-7)), this means (g o h)(-7) = 96
