Back

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

Front

What are the solutions of a quadratic equation?

Back

The solutions of a quadratic equation are the values of x that make the equation equal to zero, also known as roots or x-intercepts.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the highest or lowest point of the parabola, depending on the direction it opens.

Front

What does it mean for a function to have no solution?

Back

A function has no solution when there are no x-values that satisfy the equation, often indicated by a contradiction.

Front

What are roots of a quadratic function?

Back

Roots are the x-values where the graph of the function intersects the x-axis.

How do you determine the range of a quadratic function?

Back

To determine the range, find the vertex and consider the direction the parabola opens (upward or downward).
