Rolle's theorem worksheet

If a smooth curve comes back to the same height it started at, it has to turn round somewhere in between. That turning point is where the derivative is zero, and that is the whole theorem.

How to do these

Find the value of c for f(x)=x2−4x on [0,4]

  1. Both ends are at zero, so the theorem applies.
  2. The derivative is 2x minus 4.
  3. That is zero at x equals 2.

The answer is c=2.

Where students go wrong

Checking only that the function is continuous. It also has to come back to the same height: if the two ends are at different heights there is no reason for a flat spot, and the mean value theorem is the one that applies instead.

Also called Rolle theorem, derivative equals zero or horizontal tangent on an interval.

Questions about these worksheets

Yes. Every rolle's theorem 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.

Calculus is usually taken around 12th grade or a first college course, 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 rolle's theorem 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.

Checking only that the function is continuous. It also has to come back to the same height: if the two ends are at different heights there is no reason for a flat spot, and the mean value theorem is the one that applies instead.
