Nov 19, 2024 · Finding the Axis of Symmetry of the Parabola y = 2x 2 + 8x + 5. Given, y = 2x 2 + 8x + 5 …..(i) Comparing the equation (i) of the parabola with the standard form y = ax 2 + bx + c, we have. a = 2, b = 8, and c = 5. Using the formula, the axis of symmetry is ${x=-\dfrac{b}{2a}}$ ⇒ ${x=-\dfrac{8}{2\times 2}}$ ⇒ ${x=-2}$ Thus, the axis of ...

The axis of symmetry is an imaginary line that divides a figure into two identical parts such that each part is a mirror reflection of one another. When the figure is folded along the axis of symmetry, the two identical parts superimpose. A parabolahas one line of symmetry. The axis of the symmetry is the straight line that divides a parabola into ...
The quadratic equation in standard formis, y = ax2+ b x+c where a, b, and c are real numbers. Here, the axis of symmetry formula is: x = - b/2a.
The quadratic equation in vertex form is, y = a (x-h)2 + k where (h, k) is the vertex of the parabola. Here, the axis of symmetry formula is x = h. The axis of symmetry always passes through the vertex of the parabola. Thus identification of the vertex helps us to calculate the position of the axis of symmetry. Axis of symmetry formula for a parabo...

Jan 5, 2024 · Plug your numbers into the axis of symmetry formula. 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. 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.
