Test #2

Front

What is the rate of change of a graph?

Back

The rate of change of a graph refers to how much the output (y-value) changes for a given change in the input (x-value). It is often represented by the slope (m) of the line.

Front

What does it mean for y to be a function of x?

Back

For y to be a function of x, each input (x-value) must correspond to exactly one output (y-value). This means that no x-value can be repeated with a different y-value.

Front

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

Back

Front

How do you determine the range of a function from its graph?

Back

The range of a function is the set of all possible output values (y-values). It can be determined by looking at the vertical extent of the graph.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the graph of the equation crosses the y-axis. It represents the value of y when x is 0.

Front

What does a slope of 0 indicate about a graph?

Back

A slope of 0 indicates that the graph is a horizontal line, meaning that there is no change in y as x changes.

Front

What does an undefined slope indicate about a graph?

Back

An undefined slope indicates that the graph is a vertical line, meaning that there is no change in x as y changes.

Front

How can you identify a function from a set of ordered pairs?

Back

To identify a function from a set of ordered pairs, check that each x-value is unique and does not repeat with a different y-value.

Front

What is the formula for calculating the slope between two points?

Back

Front

What does the term 'domain' refer to in a function?

Back

The domain of a function refers to the set of all possible input values (x-values) that the function can accept.
