Y = 2x^2 + 3<br> im looking for how to find the axis of symmetry
andre [41]

The axis of symmetry of the quadratic equation y = 2x^2 + 3 is x = 0

<h3>How to determine the axis of symmetry?</h3>

The equation is given as:

y = 2x^2 + 3

Differentiate the above equation with respect to x

y' = 4x + 0

This gives

y' = 4x

Set the equation to 0

4x = 0

Divide both sides by 4

x = 0

Hence, the axis of symmetry is x = 0
