So, here's the problem:

1) Let f be the function defined by $\displaystyle f(x) = -A + ln(x^2)$, where A is the number of letters in your last name. (For me, that would be 6).

(a) Find the exact zeros of f (using algebra, not your calculator).

(b) Write an equation for the tangent line to the graph of f at x = -1.

Can someone explain to me how to get started solving these questions?
