Linear vs NonLinear Functions

Front

What is a linear function?

Back

A linear function is a function that creates a straight line when graphed. It has a constant rate of change and can be expressed in 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 create a straight line when graphed. It can have curves, bends, or changes in direction, and does not have a constant rate of change.

Front

How can you identify a linear function from its graph?

Back

A linear function can be identified by its straight line graph. If the graph has a constant slope and does not curve, it is linear.

Front

How can you identify a nonlinear function from its graph?

Back

A nonlinear function can be identified by its curved or bent graph. If the graph changes direction or has varying slopes, it is nonlinear.

Front

What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the function. It indicates how much the y-value changes for a given change in the x-value.

Front

What is the y-intercept of a linear function?

Back

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

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

Can a linear function have a negative slope?

Back

Yes, a linear function can have a negative slope, which means that as the x-value increases, the y-value decreases.

Front

What is an example of a nonlinear function?

Back

An example of a nonlinear function is y = x^2, which creates a parabolic curve when graphed.

Front

What is the difference between a linear and a nonlinear equation?

Back

A linear equation represents a straight line and has a constant rate of change, while a nonlinear equation represents a curve and has a varying rate of change.
