4. a) Sketch the graph of the function f (x) = Vx + 3 (include 4 distinct transformed points) / 4 b) Draw a tangent line for the function at the point when x = 1. c) Estimate the IROC when x = 1 by using two points to calculate the slope of the tangent. (Please round your slope to the nearest tenth)
