We need to find f(5) and g(-3)

First, we will solve f(5), for this, we have the following function:

[tex]\begin{gathered} f(x)=-3x-1 \\ f(5)=-3\cdot(5)-1 \\ f(5)=-15-1 \\ f(5)=-16 \end{gathered}[/tex]

Second, we will solve g(-3), for this, we have the following function:

[tex]\begin{gathered} g(x)=4x^2-x \\ g(-3)=4(-3)^2-(-3) \\ g(-3)=4\cdot9+3 \\ g(-3)=36+3 \\ g(-3)=39 \end{gathered}[/tex]

In conclusion, f(5) = -16 and g(-3) = 39
