What is g(f(x)) when f(x) = 3x + 1 and g(x) = 4x2 - 4? a) g(f(x)) = 12x2 - 11 b) g(f(x)) = 13x2 + 10x c) g(f(x)) = 36x2 + 24x d) g(f(x)) = 144x2 + 96x + 12

C) g(f(x)) = 36x^2 + 24x

Step-by-step explanation:

g(f(x)) when f(x) = 3x + 1 and g(x) = 4x^2 - 4

g(f(x)) = 4(3x + 1)^2 - 4

g(f(x)) = 4(9x^2 +  6x +1) - 4

g(f(x)) = 36x^2 + 24x + 4 - 4

g(f(x)) = 36x^2 + 24x

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
