What does the vertex of a quadratic function represent?

Back

The vertex represents the highest or lowest point of the parabola, depending on its orientation.

Front

How do you determine the range of a quadratic function?

Back

To determine the range, find the vertex and identify the minimum or maximum value of the function.

What is the significance of the coefficient 'a' in a quadratic function?

Back

The coefficient 'a' determines the direction of the parabola: if 'a' is positive, it opens upwards; if negative, it opens downwards.

Front

What is the difference between domain and range?

Back

Domain refers to all possible input values (x-values), while range refers to all possible output values (y-values) of a function.

What is interval notation?

Back

Interval notation is a way of writing subsets of the real number line, using parentheses and brackets to indicate whether endpoints are included.
