# How do you find the axis of symmetry, and the maximum or minimum value of the function y = (x – 5)^2 + 10?

$x = 5$ is the axis of symmetry
From the equation: $y = {\left(x - 5\right)}^{2} + 10$, vertex is at $\left(h , k\right) = \left(5 , 10\right)$
Axis of symmetry is $x = 5$ a vertical line passing through the vertex
