Let f(x) = x2 and g(x) = x − 3. evaluate the expression (g ° g)(7)

This is a function composition with g(x) composed with g(x), then evaluated at 7.
g(g(x)) =
g(x - 3) =
x - 3 - 3 =
x - 6 =
7 - 6 = 1
OR
You could but 7 in the g(x) function. Get that result, and put it in g(x) again.
g(7) = 7 - 3 = 4
g(4) = 4 - 3 = 1

Either way, the answer is 1
