I'm having a really difficult time solving this one calculus problem. It goes as follows: Find the equation of the normal to the curve at x=1. I'm not looking for an answer, but rather some guidance on how to approach and solve the problem.

If you apply the changes below to the absolute value parent function, f(x)=\x\, which of these is the equation of the new function? shift 2 units to the left shift 3 units down a. g(x)=\x-3\-2 b. g(x)= \x-2\-3 c. g(x)= \x+3\-2 d. g(x)= \x+2\-3
