Question

Given the functions f(x) = 7x + 13 and g(x) = x2 + 2, which of the following functions represents f[g(x)] correctly?
f[g(x)] = 7x2 + 27
f[g(x)] = 7x2 + 15
f[g(x)] = 49x2 + 182x + 169
f[g(x)] = 49x2 + 182x + 171

Answer 1

Answer:

f[g(x)] = 7x2+27

Step-by-step explanation:

This represents the function of f[g(x)] because it replaces the x in f(x) with g(x)

f[g(x)] = 7(x2+2)+13

f[g(x)] = 7x2+14+13

f[g(x)] = 7x2 +27

Answer 2
