18x^2-3

Step-by-step explanation:

f(g(x))=2(x^2-4)+5

=2x^2-8+5

=2x^2-3

Substitute x with 3x

2(3x)^2-3

=2(9x^2)-3

18x^2-3

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

6 and 24

step-by-step explanation:

6 x 4 = 24
