MATLAB code, Need help with these 2 questions for matlab. I know how to do these in paper but am having trouble figuring out the code in matlab, Thank you!

Putting it All Together In this set, you will investigate a function with some points on the graph not having a slope. Put your MATLAB commands in a new section of your Live Script along with text to answer questions and make appropriate comments to demonstrate your understanding Define and plot the function p(x) = x^2-5x+6l over the interval [1,4]. Next redefine the dq using the new function, p(x). 1. Find the slopes of the tangent lines for the graph at x = 1.5, 2.5 and 3.5. Explain what you find. Be sure you are using limits in the dq function as h goes to 0. Why are the slopes positive, negative or zero? 2. You will further analyze this graph in a few different ways at x = 2. As you will see, the results are very different from what you saw in #1. Geometrically Plot p(x) and secline(2,h,x) together over the interval [1,4] for small values of h, namely h 0.001 and h = -0.001. Explain why the plots are so different depending on whether his positive or negative. Limits Find the limit of da(2,5) as h approaches 0. Would you expect to get a numerical answer if you found the left- and right-hand limits? Why? (Refer back to the previous lab to see how to compute a one-sided limit.) Then compute the left and right-hand limits for da(2,h) as h approaches 0. What does the two values for the Left- and Right- limits for the slopes of p(x) at x = 2 tell you? 3. There is another point on the graph where the limit of the dq function does not exist. Where is it? Analyze the graph in the same way (geometrically and with limits)
