Be careful when simplifying with negatives. If the "b" term is negative in your original equation, it will become positive when substituted and simplified in the axis of symmetry formula. If your quadratic equation lacks a "b" term, the axis of symmetry is automatically x = 0. The "c" ...

A line l is called an axis of symmetry of a graph if it is possible to pair the points of the graph in such a way that l is the perpendicular bisector of the segment joining each pair. A point O is called point of symmetry of a graph if it is possible to pair the points of th...
tofind).Here is a unit circle for this situation.Clearly the angle in the first quadrant is π/(6) and by some basic symmetry we can see that the terminalline for the second angle must form an angle of π/(6) with the negative x-axis as shown above and so it will be (5π)/6...
Similarly, y-intercept refers to the y-coordinate of a point where a graph crosses the y-axis.To find the intercepts, we either need the graph or the equation defining the graph. Since we are given only two coordinate points, you will need to frame the equation using these points and ...
Section 3.1 Day 2 – Quadratic Functions After this section you should be able to: Graph a quadratic function with and without a calculator. Find the coordinates of two additional points on the parabola. Find the x – intercepts of a quadratic function. Find the quadratic equation, given a ...
The vertex of a quadratic equation or parabola is the highest or lowest point of that equation. It lies on the plane of symmetry of the entire parabola as well; whatever lies on the left of the parabola is a complete mirror image of...
