Answer:

Option 2: 27 is the correct answer.

Step-by-step explanation:

Given functions are:

$f(x) = x^2-2\\g(x) = 4f(x) - 1$

As we can see that the function g(x) in written in terms of f(x), first of all we have to find g(x) by putting the value of f(x) in g(x)

So putting f(x) = x^2-2 in g(x)

$g(x) = 4(x^2-2)-1\\= 4x^2-8-1\\=4x^2-9$

As g(-3) has to be found, putting x=-3 in g(x)

$g(-3) = 4(-3)^2-9\\= 4(9)-9\\=36-9\\=27$

Hence

Option 2: 27 is the correct answer.
