# What is the axis of symmetry and vertex for the graph y = x^2 + 3?

The Aos (axis of symmetry) is $x = 0$, the vertex is $\left(0 , 3\right)$
The parabola lands directly in the middle of the y axis, which gives it an aos of $0$.
When graphed, the lowest point, or vertex on the graph is $\left(0 , 3\right)$.
