If #f(x) = x^2 + 3x# and #g(x) = 4x - 1#, what is #(g@f)(-3)#?
Lily AndersonIt is
First since both functions are polynomials their composition can be defined.

Benjamin AchtenbergTo find (g@f)(-3), first evaluate f(-3) to get -6. Then, substitute this result into g(x) to get g(-6). Evaluating g(-6) gives -25. Therefore, (g@f)(-3) = -25.

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.
