You may need these tools for some of the problems in Aleks. Check it out - select the degree of polynomial, type in your points over the example points in the bar, press the red square on the right and bam! At DESMOS, for a 4th degree, type the following: y ~ ax₁⁴ + bx₁³ + cx₁² + dx₁ + e

At Wolfram, type something like this in the orange rectangular search bar: polynomial of degree 4 {{-3,-29},{-2,6},{-1,3},{0,-2},{1,3},{2,6},{3,-29}} Thanks! Dr. Dlabach

Note!! This is not a question in actuality. It was a post form our professor. I just want a contribution for it. Kindly contribute to the above from our professor substantively for participation point. Thanks.
