Please help and answer in detail. Thank you.(6 points) Input Y1=e-x in the Y= editor. Graph it using the following window: [0,4][0,1]=[xmin,xmax][Ymin,Ymax]. Scale the horizontal axis by 1 and the vertical axis by 0.1. Copy the graphq,(4 points) First, use 2 subintervals 0,2 and 2,4. Evaluate your rate function, Y1=e-x, at the left-hand endpoint of each of these interval, x=0 and x=2. On the TBLSET Menu, set TbiStart to 0 and Tbl to 2. View the table and record the values in the table below. Write down all the digits your calculator displays.\table[[x,Y1(x)
