What is the end behavior of a function as x approaches negative infinity?

Back

The end behavior of a function as x approaches negative infinity can vary; it may approach a specific value, infinity, or negative infinity depending on the function's characteristics.

What does a residual plot indicate about a linear regression model?

Back

A residual plot shows the difference between observed and predicted values. If the residuals are randomly distributed, it indicates a good fit; if they display a pattern, it suggests a poor fit.

Front

What does it mean if a function is undefined at a certain point?

Back

Front

What is the difference between a linear function and a nonlinear function?

Back

A linear function has a constant rate of change and can be represented by a straight line, while a nonlinear function does not have a constant rate of change and can be represented by curves.

Front

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

Back

The y-intercept is the point where the graph of a function crosses the y-axis, representing the output value when the input is zero.
