# How do find the vertex and axis of symmetry, and intercepts for a quadratic equation y=2x^2 + 1?

Jul 13, 2018

Vertex (0,1)
Axis of symmetry $x = 0$ or the y axis

#### Explanation:

x coordinate for axis of symmetry is found using $\frac{- b}{2 a}$

$\frac{0}{4} = 0$ when $x = 0 , y = 1$

It is a $\cup$ shaped parabola with the minimum at (0,1) so it does not cross the x axis
