Front

What are the zeros of a function?

Back

The zeros of a function are the values of x for which the function equals zero. They are the x-intercepts of the graph.

Front

What is a system of linear equations?

Back

A system of linear equations is a set of two or more linear equations with the same variables. The solution is the point(s) where the equations intersect.

Front

What does the domain of a function represent?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is an absolute maximum on a graph?

Back

An absolute maximum is the highest point over the entire domain of a function.

Front

How do you find the zeros of a quadratic function?

Back

To find the zeros of a quadratic function, set the function equal to zero and solve for x using factoring, completing the square, or the quadratic formula.

Front

What is the quadratic formula?

Back

Front

What is the slope-intercept form of a linear equation?

Back

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) has exactly one output (y-value).

Front

How do you determine if a point is a maximum or minimum on a graph?

Back

To determine if a point is a maximum or minimum, analyze the slope of the function at that point. If the slope changes from positive to negative, it's a maximum; if it changes from negative to positive, it's a minimum.
