I need help with this in graph calculator

Finding A Maximum Point on a Graph 1. Graph the function flx) = -1x2 + 3x + 10 and use a graphing calculator to find the maximum point. Enter the function into your calculator. Y1 = 2. Hit Zoom 6. Does the top of the graph show in this standard window? Hit the Window key and change the y-max to 20. Hit Graph. Does the top of the graph show now? 3. To find the maximum, hit 2"d CALC {What number?) Choose an x-value that is to the left of the top of the graph: Key in that number and you can hit ENTER. Choose an x-value that is to the right of the top of the graph: Key in that number and hit ENTER twice. 4. Name the ordered pair given as the maximum point: Remember that by definition, the maximum is actually the y-yalue of the highest point. So the maximum is at x: S. I would also like to assess your graphing skills with this assignment, so on the next page I'd like you to create some ordered pairs and graph the function. Pfeose no to the next oooe
