What is the vertex form of a quadratic function?

Back

The vertex form of a quadratic function is given by f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola.

Front

How do you identify the vertex of the quadratic function y = (x - 1)² + 2?

Back

The vertex is (1, 2). This is derived from the vertex form f(x) = a(x - h)² + k.

Front

What does the 'a' value in the vertex form of a quadratic function indicate?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0) and the width of the parabola.

Front

What is the standard form of a quadratic function?

Back

The standard form of a quadratic function is f(x) = ax² + bx + c.

Front

How can you convert from standard form to vertex form?

Front

How do you determine if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through it intersects the graph at most once (Vertical Line Test).

Front

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

Back

The vertex represents the maximum or minimum point of the parabola, depending on the direction it opens.
