Unit 4 Test Review

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.

What does it mean for a function to be LINEAR?

Back

Front

How do you express a function in FUNCTION NOTATION?

Back

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

What is the slope in a linear equation?

Back

The slope (m) in a linear equation represents the rate of change of the function, indicating how much y changes for a unit change in x.

Front

How do you determine if a function is LINEAR or NONLINEAR?

Back

A function is LINEAR if it can be graphed as a straight line; otherwise, it is NONLINEAR.

Front

What is the y-intercept in a linear equation?

Back

Front

Back

This equation represents a linear function where the slope is 3 and the y-intercept is 0.

Front

How can you identify the DOMAIN from a graph?

Back

The DOMAIN can be identified by looking at the x-values that the graph covers; it includes all x-values for which the graph exists.
