What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of a function intersects the y-axis, represented as (0, y).

What is the x-intercept of a function?

Back

The x-intercept is the point where the graph of a function intersects the x-axis, represented as (x, 0).

How do you find the domain of a rational function?

Back

To find the domain of a rational function, identify values that make the denominator zero and exclude them from the domain.

Front

What is the significance of intercepts in a function?

Back

Intercepts help identify where the function crosses the axes, providing key points for graphing.
