# Axis of symmetry formula - How Do You Find the Axis of Symmetry for a Quadratic Function?

Likewise, what is the formula for the vertex? The vertex of a parabola is the point where the parabola crosses its axis of symmetry.

This useful form of the line equation is sensibly named the "slope-intercept form".

This is the key point to determine its equation.

In each case, memorization is probably simpler than completing the square.

Axis of Symmetry The axis of symmetry is an imaginary straight line that divides a shape into two identical parts, thereby creating one part as the mirror image of the other part.
Axis of Symmetry Formula The axis of symmetry formula is applied on quadratic equations where the standard form of the equation and the line of symmetry are used.
The graph of a polynomial or function reveals many characteristics that would not be clear without a visual representation.

Using the axis of symmetry formula, x = -b/2a x = - (0)/2 (4) = 0 Therefore, the axis of symmetry of equation y = 4x 2 is x = 0. Identification of the Axis of Symmetry Using the formula learned in the previous section, letβs identify the axis of symmetry for the given parabola. 1) Consider equation y = x 2 β 3x + 4.

Here, equation of axis of symmetry is \$\$ X = -b / 2a \$\$ Vertex Form: The vertex form of the quadratic equation is, \$\$ Y = a (xβh)^2 + k \$\$ Where, (h, k) = vertex of the parabola. In the vertex form, we can say x = h, because the vertex and the axis of symmetry are on the same straight line.

Question #4: Mr. Matthews drops down into a snowboard halfpipe shaped like a parabola. The equation that matches the shape of the halfpipe is y = x 2 β 9 x + 8 in standard form. Use the equation to determine the axis of symmetry. Axis of Symmetry: x = 3. Axis of Symmetry: x = 3.5. Axis of Symmetry: x = 4.
