Question

I have a fill in the answer question for my study guide and I'd rather know how to figure this out now before the test.
For f(x) = 1/x^2 - 3 find f(3) and f(2+h)

I got f(3) I think, I just plugged in 3 for x but I'm confused how to get f(2 + h) it's a bit more confusing to me.

Thank you for any help :)

Answer 1

is the function

\[\large f(x) = \frac{1}{x^2 - 3}\]

OR is the function

\[\large f(x) = \frac{1}{x^2} - 3\]
