Front

What is the standard form of a quadratic equation?

Back

y = ax^2 + bx + c

Front

What does the 'a' value in the quadratic equation affect?

Back

The direction and width of the parabola.

Front

What is the axis of symmetry in a quadratic function?

Back

The vertical line that divides the parabola into two mirror images, given by x = -b/(2a).

Front

What is the vertex form of a quadratic equation?

Back

y = a(x - h)^2 + k, where (h, k) is the vertex.
