Answer:

B) f(g(x)) = 15x² + 18

Step-by-step explanation:

Plug the entire equation of g(x) in for the x in f(x)

f(g(x)) = 5(3x² + 3) + 3

f(g(x)) = 15x² + 15 + 3

f(g(x)) = 15x² + 18

-2.105 as a fraction?
Bezzdna [24]
The easiest way is if it doesn't need to be simplified. Multiply -2.105 by \frac{1000}{1000}. You get the fraction -\frac{2105}{1000}. While this is technically the answer, you can simplify this down to \frac{421}{200}. Because 421 is a prime number, this can not be simplified any further. Therefore, the solution is \frac{421}{200}.

\frac{421}{200}.
