Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input from a given set.

Front

What is 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.

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.

Front

How do you represent the domain of a function using inequalities?

Back

Front

What does it mean for a function to be linear?

Back

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise over run).

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or equal to the other.

Front

How do you find the range of a linear function given its domain?

Back

To find the range, substitute the domain values into the function and determine the resulting output values.

Front

What is a quadratic function?

Back

Front

What is the vertex of a quadratic function?

Back

The vertex of a quadratic function is the highest or lowest point on the graph, depending on the direction of the parabola.
