Question

1. Dressing up the graph with text, gtext, xlabel, ylabel, and tit le: Plot y = exp(r) in the interval [-3, 3] using a solid line. Now plot a linear approximation of e (i.e., y = x) using a dashed line and a 1 + r + using a dotted line. Title the plot "Gross Approximations of exp(x)." Label the y-axis as text to label the exp(a) quadratic approximations of exp(r) appropriately. Set axes limits to [-3, 3, -5, 15). quadratic approximation of e (i.e., "Approximations of exp(x)" and the r-axis as "x". Use curve at position (2, 8). Use gtext to label the linear and
