Graphing conic sections worksheet for Algebra 2

Once each conic makes sense on its own, the real test is telling them apart. Two squared terms added is an ellipse, subtracted is a hyperbola, added with the same denominator is a circle, and only one squared term is a parabola.

Also taught in Precalculus, at its own level and with its own examples.

How to do these

Graph (x−1)216+(y+2)29=1

  1. Both terms are squared and they are added, so it is an ellipse or a circle.
  2. The denominators differ, so it is an ellipse.
  3. Center (1, -2), reaching 4 sideways and 3 up and down.

The answer is Center (1,−2), a=4, b=3.

Where students go wrong

Jumping to the shape before reading the signs. A minus between the two squared terms is always a hyperbola however the numbers look, and one squared term is always a parabola.

Also called graphing conics, mixed conic sections or conic graphs.

Questions about these worksheets

Yes. Every graphing conic sections 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 conic sections 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.

You pick from 8: graph a circle, a parabola, an ellipse, a hyperbola, focus and directrix from the equation, vertices, co-vertices and foci, asymptotes and foci and classify from general form and give the key points. Tick as many as you want and set how many of each, or let it spread them evenly.

Jumping to the shape before reading the signs. A minus between the two squared terms is always a hyperbola however the numbers look, and one squared term is always a parabola.
