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 .

(c) Graph the quadratic function. \[ f(x)=(x … WebOct 6, 2024 · We define the x intercepts as the points on the graph where the graph crosses the x axis. If a point is on the x axis, then the y coordinate of the point is 0. Hence to find the x intercepts, we set y = 0 and solve. Example 1.2. 6: x intercepts Find the x intercepts of (1.2.21) y = x 2 + x − 2 Solution We set y = 0 so that
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. 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). …
