Does the graph of a polynomial function contain a break?

Back

Never. Polynomial functions are continuous everywhere.

What is a discontinuity in a function?

Back

A point where a function is not continuous, meaning it does not have a limit or the limit does not equal the function's value.

What is a removable discontinuity?

Back

A point where a function is not defined, but can be made continuous by redefining the function at that point.

What is a jump discontinuity?

Back

A point where the left-hand limit and right-hand limit exist but are not equal.

What is an infinite discontinuity?

Back

A point where the function approaches infinity or negative infinity as x approaches a certain value.

How can you identify a removable discontinuity in a rational function?

Back

If the function can be simplified and the factor causing the discontinuity cancels out.

What is the Intermediate Value Theorem?

Back

If a function is continuous on [a, b], then it takes every value between f(a) and f(b).
