Characteristics of Quadratics

Front

What is the domain of a quadratic function?

Back

All real numbers.

Front

What do we call the highest or lowest point of a quadratic?

Back

Vertex.

Front

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

Back

y ≤ k, where k is the y-coordinate of the vertex.

Front

What does 'c' represent in the quadratic equation y=ax²+bx+c?

Back

y-intercept.

Front

What is the y-intercept of the function y=-2x²+8x-6?

Back

(0, -6).

Front

What is the axis of symmetry in a quadratic function?

Back

x = -b/(2a).

Front

What is the standard form of a quadratic function?

Back

y = ax² + bx + c.

Front

What does the 'a' value in a quadratic function determine?

Back

The direction of the parabola (upward if a > 0, downward if a < 0).

Front

How do you find the vertex of a quadratic function in standard form?

Back

Use the formula x = -b/(2a) to find the x-coordinate, then substitute back to find the y-coordinate.

Front

What are the zeroes of a quadratic function?

Back

The x-values where the function equals zero.
