Front

Convert to Factored Form: x^2 - 10x + 24

Back

The factored form is (x - 6)(x - 4).

Front

Convert the equation from vertex form to standard form: y = -5(x + 2)^2 - 10

Back

The standard form is y = -5x^2 - 20x - 30.

Front

Convert to standard form: f(x) = x^2 + 3x - 18

Back

The standard form is (x + 6)(x - 3).

Front

What is the vertex of the parabola given by the equation y = a(x - h)^2 + k?

Back

The vertex is the point (h, k).

Front

How do you find the x-intercepts of a quadratic function?

What is the standard form of a quadratic function?

Back

The standard form is f(x) = ax^2 + bx + c.

Front

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

Back

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