Spiral Review - Quadratics and Functions

What is the range of a quadratic function that opens downwards?

Front

What is the domain of a quadratic function?

Back

The domain of a quadratic function is all real numbers, represented as (-∞, ∞).

Front

What does the vertex of a quadratic function represent?

Back

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

Front

How do you determine if a quadratic function has a maximum or minimum value?

Back

If the leading coefficient (a) is positive, the function has a minimum value. If a is negative, it has a maximum value.

Front

What is the standard form of a quadratic function?

Back

Front

Back

This represents a transformation of the basic quadratic function, where (h, k) is the vertex, 'a' determines the width and direction of the parabola.

Front

What does it mean for a quadratic function to be 'narrow' or 'wide'?

Back

A 'narrow' parabola has a larger absolute value of 'a' (|a| > 1), while a 'wide' parabola has a smaller absolute value of 'a' (|a| < 1).
