Front

How do you find the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined. To find the domain, identify values that cause division by zero or result in taking the square root of a negative number.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce. It can be determined by analyzing the function's behavior and any restrictions on the output.

Front

What is an inflection point?

Back

An inflection point is a point on the graph of a function where the concavity changes, meaning the function changes from being concave up to concave down or vice versa.

What is a sign analysis chart?

Back

A sign analysis chart is a tool used to determine the sign (positive or negative) of a function over different intervals. It involves identifying critical points (roots and asymptotes) and testing intervals between these points.
