Front

What does the x-intercept of a graph represent?

Back

The x-intercept is the point where the graph crosses the x-axis, representing the value of x when y equals zero.

Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point on the graph of a quadratic function, depending on its orientation.

Front

How do you find the solution to a system of equations?

Back

You can find the solution by graphing the equations and identifying the point of intersection, or by using substitution or elimination methods.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is a linear function?

Back

Front

What does it mean for a function to be quadratic?

Back

Front

What is the axis of symmetry in a quadratic function?

Back

Front

What is a zero of a function?

Back

A zero of a function is a value of x that makes the function equal to zero, indicating where the graph intersects the x-axis.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function; it represents how much y changes for a unit change in x.
