Question

2.) Given the function f (x) = 5x2 - 2, find f(-3). Please show your work.

Answer 1

So the function is:

`f(x)=5x^2-2`

and f(-3) will be replacing the x = -3 in the original function:

`f(-3)=5(-3)^2-2`

and now we can solve the operations:

`\begin{gathered} f(-3)=5\cdot9-2 \\ f(-3)=45-2 \\ f(-3)=43 \end{gathered}`
