What is a piecewise function?

Back

A piecewise function is a function that is defined by different expressions or formulas for different intervals of its domain.

How do you evaluate a piecewise function at a specific point?

Back

To evaluate a piecewise function at a specific point, determine which interval the point falls into and then use the corresponding expression to find the function's value.

What is a discontinuity in a function?

Back

A discontinuity in a function is a point at which the function is not continuous, meaning there is a break, jump, or hole in the graph.

What are the types of discontinuities?

Back

The types of discontinuities include infinite discontinuity, removable discontinuity, and jump discontinuity.

What is an infinite discontinuity?

Back

An infinite discontinuity occurs when the function approaches infinity or negative infinity as it approaches a certain point.

What is a removable discontinuity?

Back

A removable discontinuity occurs when a function is not defined at a point, but can be made continuous by defining it at that point.

What is a jump discontinuity?

Back

A jump discontinuity occurs when the left-hand limit and right-hand limit of a function at a certain point exist but are not equal.

How do you find the value of a function at a point where it is undefined?

Back

If a function is undefined at a certain point, it means that the function does not have a value at that point, often due to division by zero or a discontinuity.

What does it mean for a function to be continuous at a point?

Back

A function is continuous at a point if the limit of the function as it approaches that point equals the function's value at that point.

Front

How do you determine the value of x for a given f(x)?

Back

To determine the value of x for a given f(x), set the function equal to the given value and solve for x.
