Write a script that numerically calculates the slopes for the function y = ex. Use x-values that range from 0 to 10 in increments of 0.1. Using these slopes, calculate the equation of a line that is tangent to the function at x = 8.3. Plot this tangent line overlaid with the original function within the same figure. Set the x-axis limits to [6, 10] and the y-axis limits to [-0.5e4, 2.5e4].
