What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line. It has the form f(x) = mx + b, where m is the slope and b is the y-intercept.

What is a nonlinear function?

Back

A nonlinear function is a function that does not form a straight line when graphed. It can include curves, parabolas, and other shapes that do not have a constant rate of change.

How can you identify a linear function from its graph?

Back

A linear function can be identified by its straight line graph, which has a constant slope and does not curve.

What is the slope of a linear function?

Back

The slope of a linear function is the ratio of the change in the y-coordinate to the change in the x-coordinate between any two points on the line.

What does it mean for a function to be quadratic?

Back

A quadratic function is a type of nonlinear function that can be expressed in the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a ≠ 0.

Front

How does the graph of a quadratic function differ from a linear function?

Back

The graph of a quadratic function is a parabola, which can open upwards or downwards, while the graph of a linear function is a straight line.

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

Back

The y-intercept is the point where the graph of the function crosses the y-axis, indicating the value of the function when x = 0.
