Algebra 2 even and odd functions worksheet

Replace x with minus x and see what comes back. The same function means even, everything flipped in sign means odd, and anything else means neither.

How to do these

f(x)=3x4−2x2

  1. Replace x with minus x.
  2. Both powers are even, so nothing changes sign.
  3. f of minus x is the same as f of x.

The answer is Even.

Where students go wrong

Assuming a function has to be one or the other. Most are neither, and a single odd term mixed in with even ones is enough to spoil both.

Also called even or odd functions, symmetry of functions or function symmetry.

What you can put on this worksheet

Even, odd or neither
Even, odd or neither? f(x)=5x−4x3 → Odd
From a table
Is the function even, odd or neither?x−2−1012f(x)5−707−5 → Odd
Rational and radical formulas
Even, odd or neither? f(x)=∣x∣−6x2+7 → Even
Symmetry of an equation
Test for symmetry about the x-axis, the y-axis and the origin: y=∣x∣+1 → y-axis only

Questions about these worksheets

Yes. Every even and odd 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 even and odd 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 three 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 4: even, odd or neither, from a table, rational and radical formulas and symmetry of an equation. Tick as many as you want and set how many of each, or let it spread them evenly.

Assuming a function has to be one or the other. Most are neither, and a single odd term mixed in with even ones is enough to spoil both.
