Graphing Quadratic Functions

quadratic function the formula that can be used to find the real solutions of the quadratic equation
parabola the U-shaped graph of a quadratic function
vertex the lowest or highest point on a parabola
axis of symmetry the vertical line that divides a parabola into two symmetric parts
focus a fixed point on the interior of a parabola that lies on the axis of symmetry
zero an x-value for which f(x) = 0; a zero is located at the x-intercept of the graph of the function
maximum value the y-coordinate of the vertex of the graph of y = ax^2 + bx + c when a < 0
minimum value the y-coordinate of the vertex of the graph of y = ax^2 + bx + c when a > 0
vertex form A quadratic function of the form y = a(x - h) + k, where a does not equal 0
