Graphing polynomial functions worksheet

Factored form hands you the zeros, and the degree and the leading sign tell you what the two ends do. Mark the zeros, decide the ends, and the curve has to weave between them.

How to do these

Graph y=(x+2)(x−1)(x−3)

  1. The zeros are -2, 1 and 3.
  2. Three factors and a positive lead, so it comes up from the bottom left and leaves top right.
  3. It crosses at each zero, so it turns twice between them.

The answer is Zeros −2,1,3, ends down then up.

Where students go wrong

Getting the ends the wrong way round. An odd number of factors sends the two ends opposite ways and an even number sends them the same way, with the leading sign deciding which. The other slip is forgetting the curve has to turn between consecutive zeros.

Also called polynomial graphs, end behavior graphs or plotting polynomials from factors.

Questions about these worksheets

Yes. Every graphing polynomial functions sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.

Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.

Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.

Algebra 2 is usually taken around 10th or 11th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.

Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.

That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the graphing polynomial functions questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.

Yes. There are two levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.

Getting the ends the wrong way round. An odd number of factors sends the two ends opposite ways and an even number sends them the same way, with the leading sign deciding which. The other slip is forgetting the curve has to turn between consecutive zeros.
