Question

Given f(x) = x − 7 and g(x) = x2 .

Find g(f(4)).

g(f(4)) =
]

Answer 1

9

Explanation:

for f(x) = x - 7, f(4) = 4 - 7 = -3

for g(f(4)) = x^2, since f(4) = -3

g(-3) = (-3)^2 = 9

Answer 2

9514 1404 393

Answer:

g(f(4)) = 9

Explanation:

Put the argument value where the variable is and do the arithmetic.

g(f(4)) = g(4 -7) = g(-3) = (-3)^2

g(f(4)) = 9
