x= -4
Step-by-step explanation:
Answer:
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).
<u>g(4) can be calculated by replacing x with 4 in the equation</u>
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
