I am really struggling. This is not my expertise. Can someone help me understand this? I have a test on Tuesday and need all the input I can get.
#1) Find the equation of the tangent line to the curve f(x)= x^3 - x, at x= -1
#2) Find the equation of the tangent line to the curve f(x) = x3 - x2 + 1 at the point (1,1).
#3) If f(x) = 2-3x^2 / x^3 + x - 1, find f'(x).
#4) Find the derivative when f(x)= 5x^2 - 7x + 1. (Use the difference quotient.)
If someone could show step by step in solving, maybe I will get it? Need response as soon as possible.
