A) Find an equation of the tangent line to the curve at the given point. y = x3 − 3x + 1, (3, 19)
B) Find an equation of the line that satisfies the given conditions. Through (2, 9); parallel to the line passing through (3, 7) and (−1, 3)
C) Find an equation of the tangent line to the graph of y = g(x) at x = 3 if g(3) = −2 and g'(3) = 4. (Enter your answer as an equation in terms of y and x.)
