For this discussion, you will work in groups to visualize the area under a curve using the online graphing tool Desmos. You will use the Desmos applet for a definite integral. To get started: Group . First, review the Learn Desmos: Integrals video (desmos 1:51) @ for a few pointers on using Desmos. . Then, access the Definite Integral tool a from the Desmos site as a guest. You don't need to create an account or sign in to the site. Use the Definite Integral tool to explore the area under a curve. Complete the following. . Replace the default equation with f (x) = 3x5 - 2x-3. . First, set the limits as a = 1 and b = 2. You may need to zoom in or out to see the graph and the shaded Discussion region. . Then, experiment with a and b both being negative. . Then, let a be negative and b be positive. Try using the slider and have a and b as decimals. . Take a screenshot of one of your cases (including the right column of input information and the graph with the shaded region) to post into the discussion. Find & Post Find S2 (3a5 - 2x3) da and share the steps you used to get it
