Graphing Quadratic Functions
Term | Definition |
---|---|
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 |
