What is a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as a set of ordered pairs, a graph, or an equation.

What does the slope of a graph represent?

Back

The slope of a graph represents the rate of change of the function. It indicates how much the output (y-value) changes for a given change in the input (x-value).

How can you determine if a graph is increasing or decreasing?

Back

A graph is increasing if the y-values rise as the x-values increase, and it is decreasing if the y-values fall as the x-values increase.

What does a horizontal line on a graph indicate?

Back

A horizontal line indicates that the output (y-value) remains constant regardless of the input (x-value), meaning the function has a slope of zero.

What does a vertical line on a graph indicate?

Back

A vertical line indicates that for a given x-value, there are multiple y-values, which means it does not represent a function.

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis. It represents the output value when the input is zero.

How do you find the distance covered in a specific time interval on a graph?

Back

To find the distance covered in a specific time interval, look at the change in the y-values (distance) between the two corresponding x-values (time) on the graph.

What does it mean if a graph is stationary?

Back

A stationary graph means that the output (y-value) does not change as the input (x-value) changes, indicating no movement or change in distance.

Front

How can you identify the fastest runner from a graph?

Back

The fastest runner can be identified by the steepest slope on the graph, which indicates the greatest rate of change in distance over time.

What does it mean if a graph shows a steep slope?

Back

A steep slope indicates a rapid change in the output (y-value) for a small change in the input (x-value), suggesting a high speed or rate.
