Front

What is the standard form of a quadratic function?

Back

f(x) = ax² + bx + c.

Front

What does the 'a' in the quadratic function f(x) = ax² + bx + c represent?

Back

The coefficient that determines the direction and width of the parabola.

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 is the effect of a negative 'a' value in a quadratic function?

Back

It reflects the parabola across the x-axis.

Front

What is the axis of symmetry in a quadratic function?

Back

The vertical line that passes through the vertex, given by x = -b/(2a).

Front

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

Back

It represents the maximum or minimum point of the parabola.
