Front

What is the vertex of a parabola in standard form y = ax^2 + bx + c?

Back

The vertex is at the point (-b/(2a), f(-b/(2a))).

Front

What does the term 'y-intercept' refer to in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis.

Front

How do you find the axis of symmetry for a parabola?
