Linear vs NonLinear Functions

Front

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.

Front

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 curved or have varying slopes.

Front

How can you identify a linear function from its equation?

Back

A linear function can be identified by its equation being in the form y = mx + b, where m and b are constants.

Front

What is the slope of a linear function?

Back

The slope of a linear function is the ratio of the change in y to the change in x, often represented as 'm' in the equation y = mx + b.

Front

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

Back

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

Front

Can a function be both linear and nonlinear?

Back

No, a function cannot be both linear and nonlinear. It is classified as one or the other based on its characteristics.

Front

What is an example of a linear function?

Back

An example of a linear function is y = 3x + 2.

Front

What is an example of a nonlinear function?

Back

An example of a nonlinear function is y = x^2 or y = 1/x.

Front

How do you determine if a function is linear from a graph?

Back

A function is linear if its graph is a straight line. If the graph curves or has bends, it is nonlinear.

Front

What is the general form of a linear equation in two variables?

Back

The general form of a linear equation in two variables is Ax + By + C = 0, where A, B, and C are constants.
