What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points in that interval, the function's value at the second point is greater than the value at the first point.

Define the term 'x-intercept'.

Back

The x-intercept of a graph is the point where the graph crosses the x-axis, meaning the value of y is zero at that point.

What is a constant function?

Back

A constant function is a function that does not change its value; it remains the same for all inputs.

Front

How can you identify a constant interval on a graph?

Back

A constant interval on a graph is identified where the graph is horizontal, indicating that the function's value does not change.

What is the significance of the x-intercept in a function?

Back

The x-intercept indicates the value of x at which the function equals zero, which can be important for solving equations.
