Graphing CalculatorDescribe the endpoints. In the textbox, label and write the coordinates (t,y)for the solid points andor the holes atx=2 and x=4? Note: If a hole anda solid point are at the same point, then there isno hole.[Keepin mind that we need to use the Canvas Math Editor whenever we needto type math expressions or equations).Sample Answer: There is a hole at($,4)3,-2(-7,5)so there isno hole there.Embed a clear and easy-to-read picture of your graph (directions forembedding a picture).DesmosDescribe the endpoints. Using Desmos, place either a solid point or a hole atthe appropriate coordinates (x,y) for x=2 and x=4.Embed a clear and easy-to-read picture of your graph (directions forembedding a picture).
