Question

I hope you dont mind but I have to show my work, so if you could walk me through it, that would be awesome!

Answer 1

Given the function

$f(x)=5x^2+7x-11$

You have to calculate the value of the function when x=-3, for this, replace x with the given value

$\begin{gathered} f(-3)=5(-3)^2+7(-3)-11 \\ f(-3)=5\cdot9-21-11 \\ f(-3)=45-32 \\ f(-3)=13 \end{gathered}$
