Question

If f(x) = -2x2 - 3 and g(x) = 3x - 4, then f(g(2))=

Answer 1

If f(x) = -2x2 - 3 and g(x) = 3x - 4, then f(g(2))= f(g(2)) = -11

Explanation:

Answer 2

f(g(2)) = -11

Explanation:

f(g(2))=

First we need to find g(2)

g(x) = 3x-4

We let x=2

g(2) = 3(2) -4

6-4

=2

Now we stick the value of g(2) in for x in f(x)

f(x) = -2x^2 - 3

f(2) = -2(2)^2 -3

=-2 (4) -3

= -8 -3

=-11
