[Using Geogebra:] Let h(x) = 11 4 x 2/3 x 3 . a) By hand, find the equation of the tangent line to the graph of h(x) at x = 1. b) Use Geogebra to plot the graph of h(x) and its tangent line. You can use the command tangent((-1,6),h(x)) in the Geogebra input bar. c) Screenshot your Geogebra work, label it appropriately, and submit it with your assignment
