We know that y = -b/2a is the equation of the axis of symmetry. y = -b/2a. y = -5/2(4) y = -0.625. 3) If two points are at the same distance from the vertex of the parabola are given, then we determine the equation of the axis of symmetry by finding the midpoint of those points. Suppose the two points (3, 4) and (9, 4) are points on a parabola ...
On this page, we will practice drawing the axis on a graph, learning the formula, stating the equation of the axis of symmetry when we know the parabola's equation Explore how the graph and equation relate to the axis of symmetry , by using our interactive program below .
Aug 3, 2023 · The vertex form of a quadratic equation is y = a (x – h) 2 + k, Equation of axis of symmetry is, x = h, here (h, k) = vertex of the parabola. We obtain the vertex of the function (x, y) by substituting the value of x in the standard form of the equation and get the value of y. Let us solve some examples involving the above formulas and concepts.
Jan 5, 2024 · To calculate the axis of symmetry for a 2nd order polynomial in the form ax 2 + bx +c (a parabola), use the basic formula x = -b / 2a. [3] In the example above, a = 2 b = 3, and c = -1. Insert these values into your formula, and you will get: x = -3 / 2 (2) = -3/4. Write down the equation of the axis of symmetry.
