1. Using a series of secant lines, find approximations to the slope of the tangent to the curve 2 3x + 4 At x = 1. To form the secant lines, choose a sequence of points with x = 1.1, x = 1.01, x = 1.001, and x = 1.0001. Do not round at any point throughout your calculations. Keep as many significant digits as your calculator can carry. [5 marks] y
