Linear and Nonlinear Functions

What is a Linear Function?

Back

A linear function is a function that can be graphically represented as a straight line. It has the form y = mx + b, where m is the slope and b is the y-intercept.

What is a Nonlinear Function?

Back

A nonlinear function is a function that does not form a straight line when graphed. Its graph can be a curve, a circle, or any other shape that is not linear.

What is the slope in the linear equation y = 3x + 4?

Back

The slope is 3.

Front

What does the y-intercept represent in a linear function?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By = C, where A, B, and C are constants.

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.
