Given f(x) =x-7 and g(x)= x^2 find f(g(4))

f(g(x)) = 9

Step-by-step explanation:

Given f(x) =x-7 and g(x)= x^2 find f(g(4))

To calculate composition, first calculate g(4).

g(4) can be calculated by replacing x with 4 in the equation

g(x) = x^2

g(4) = 4^2 = 16

To calculate f(g(4)), we have to replace x in equation with the value of g(4)

f(x) = x-7

f(g(x)) = g(x) - 7

f(g(x)) = 16 - 7

f(g(x)) = 9

sorry, i can't understand your question. will later if you describe more clearly!
