What is a piecewise function?

Back

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

Front

How do you determine which part of a piecewise function to use for a given input?

Back

You evaluate the input against the conditions defined for each piece of the function to find the appropriate expression.

Front

What is a discontinuity in a function?

Back

A discontinuity is a point at which a function is not continuous, meaning it has a break, jump, or hole in its graph.

Front

Identify a function that has a discontinuity.

Back

Increasing k stretches the graph of the function vertically.

What is an absolute value equation?

Back

An absolute value equation is an equation that contains an absolute value expression, representing the distance of a number from zero on the number line.

Front

Write an absolute value equation for a situation where you hope to have 50 dollars, but your calculation may be off by $15 or less.

What is the general form of a piecewise function?

Back

A piecewise function is generally expressed as: f(x) = { expression1, if condition1; expression2, if condition2; ... }.

Front

What does it mean for a function to be continuous?

Back

A function is continuous if there are no breaks, jumps, or holes in its graph, and it can be drawn without lifting the pencil.

Front

How do you find the domain of a function?

Back

The domain of a function is found by identifying all possible input values (x-values) that will not cause any undefined expressions.
