Which of the following will form the composite function g(f(x)) shown below?

g(f(x)) = 3x2 + 1

a. f(x) = x + 1 and g(x) = 3x2
b. f(x) = 3x + 1 and g(x) = x2
c. f(x) = x2 and g(x) = 3x + 1
d. f(x) = 3x2 and g(x) = 1

answer: it's d

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
