Front

What is the domain in inequality notation for the interval [-2, 2]?

Back

Front

What is a linear function?

Back

A function that can be graphically represented as a straight line, defined by the equation y = mx + b.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x, calculated as rise over run.

Front

What is the y-intercept of a linear function?

Back

The value of y when x = 0, represented as the point (0, b) in the equation y = mx + b.

Front

How do you determine if a function is linear?

Back

A function is linear if it can be expressed in the form y = mx + b, where m and b are constants.

Front

What is the difference between domain and range?

Back

Domain refers to all possible input values (x), while range refers to all possible output values (y) of a function.

Front

What does it mean for a function to be nonlinear?

Back

A function is nonlinear if it cannot be represented by a straight line, often involving exponents, roots, or other operations.
