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

f(g(x)) = x^2 + 27.

Step-by-step explanation:

To find f(g(x))  we replace the x in  f(x) by g(x) and simplify:

f(g(x)) =   7(x^2 + 2) + 13

= 7x^2 + 14 + 13.

= 7x^2 + 27.

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
