What the answer? i’m having trouble

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

ik how do do this just give me a few minutes and i will give it to
