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 WebFunctions can be symmetrical about the y-axis, which means that if we reflect their graph about the y-axis we will get the same graph. There are other functions that we can reflect …
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. WebSep 8, 2024 · Find the vertex. Once you know the axis of symmetry, you can plug that value in for x to get the y coordinate. These two coordinates will give you the vertex of the parabola. In this case, you would plug 0 in to 2x 2-1 to get the y coordinate. y = 2 x 0 2-1 = 0 -1 = -1. The vertex is (0,-1), and the parabola crosses the y-axis at -1.
