Please answer all 4 and label them next to your answer. #1. (Differentiate the function) g(u) =(2) u + (3u) #2. Find an equation of the tangent line to the curve at the given point. Illustrate by graphing the curve and the tangent line on the same screen. f(x) = x^5 - 2x^3 + x - 1 Solution (Differentiate the function) g(u) =(2) u + (3u) take derivative g\'(u) = 2 + 3/2u.
