# How do you find #(f+g)(-2)# given #f(x)=x^2-1 and #g(x)=2x-3# and #h(x)=1-4x#?

To find (f+g)(-2), substitute x = -2 into f(x) and g(x), then add the results. (f+g)(-2) = 13.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
