Front

What does it mean if a function has no decreasing interval?

Back

If a function has no decreasing interval, it means that the function is either increasing or constant throughout its domain. For example, if a function is always increasing or flat, it does not have any intervals where it decreases.

How do you identify the y-intercept of a graph?

Back

The y-intercept of a graph is the point where the graph crosses the y-axis. It can be found by setting x = 0 in the function's equation. For example, if the y-intercept is (0, -3), it means the graph crosses the y-axis at -3.

Front

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

Back

The y-intercept is significant because it provides information about the function's value when the input is zero. It can help in understanding the function's behavior and position on the graph.

Front

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

Back

To determine the range of a function from its graph, observe the lowest and highest points on the graph. The range is the set of y-values that the graph covers.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the input values (x) increase, the output values (y) also increase. This can be identified on a graph where the slope is positive.

How do you find the x-intercept of a graph?

Back

The x-intercept of a graph is the point where the graph crosses the x-axis. It can be found by setting y = 0 in the function's equation.
