What is the definition of Range in a function?

Back

The Range of a function is the set of all possible output values (y-values) that result from using the function.

Front

How do you determine the Range from a graph?

Back

To determine the Range from a graph, look at the y-axis and identify the lowest and highest points of the graph.

Front

What is the significance of the y-axis in a coordinate plane?

Back

The y-axis represents the vertical axis in a coordinate plane, where the output values (y-values) of a function are plotted.

Front

What does the rate of change represent in a linear equation?

Back

The rate of change represents how much the output value (y) changes for a unit change in the input value (x). It is equivalent to the slope of the line.

Front

How do you identify the slope from the slope-intercept form of a linear equation?

Back

In the slope-intercept form y = mx + b, 'm' represents the slope of the line.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How can you find the slope from two points on a line?

Back

The slope can be found using the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-values increase, the y-values also increase, resulting in an upward slant of the line.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, resulting in a downward slant of the line.

Front

What is the formula for calculating the rate of change from a table of values?

Back

The rate of change can be calculated by taking the difference in y-values divided by the difference in x-values between two points.
