Need help solving asap had someone helping but Brainly crashed on me.

Answer 1

Given

The functions f and g as,

$\begin{gathered} f(x)=3x^2-3x \\ g(x)=-5x+4 \end{gathered}$

To find the value of f(-5) and g(6).

Explanation:

It is given that,

$\begin{gathered} f(x)=3x^2-3x \\ g(x)=-5x+4 \end{gathered}$

Then, for x=-5,

$\begin{gathered} f(-5)=3(-5)^2-3(-5) \\ =3(25)+15 \\ =75+15 \\ =90 \end{gathered}$

Also, for x=6,

$\begin{gathered} g(6)=-5(6)+4 \\ =-30+4 \\ =-26 \end{gathered}$

Hence, f(-5) = 90, g(6) = -26.
