Explanation:

of course there is an explanation. and a correct answer (not just a wild guess).

f(x) = 2x

g(x) = 2x² - 1

f(g(x)) means that x is first processed by g, and then the result of that is processed by f.

in other words, the whole functional expression of g becomes the input argument for f.

therefore,

f(g(x) = 2(2x² - 1) = 4x² - 2

so, the correct answer is light blue.
