WebMar 14, 2024 · The orientation of a parabola is that it either opens up or opens down; The vertex is the lowest or highest point on the graph; The axis of symmetry is the vertical line …
WebMar 14, 2024 · The axis of symmetry is the vertical line that goes through the vertex, dividing the parabola into two equal parts. If h is the x -coordinate of the vertex, then the equation for the axis of symmetry is x = h. The maximum or minimum value of a parabola is the y -coordinate of the vertex. WebApr 12, 2024 · Finding the vertex, axis of symmetry, and x-intercepts of a quadratic equation is an important skill to have in a precalculus or college algebra course. In t...
WebWhen you're graphing quadratics, you may be asked for the parabola's axis of symmetry. This is usually just the vertical line x = h, where "h" is the x -coordinate of the vertex, (h, k). That is, a parabola's axis of symmetry is usually just the vertical line through its vertex. WebUse the values of the coefficients to write the equation of axis of symmetry . The graph of a quadratic equation in the form y = ax2 + bx + c has as its axis of symmetry the line x = − b 2a . So, the equation of the axis of symmetry of the given parabola is x = − ( − 7) 2 ( 1) or x = 7 2 .
