Question

What is the axis of symmetry of the quadratic function y = -x2 + 6x + 4?​

Answer 1

x = -1

Explanation:

The reason why it is -1 is because in vertex form this would be y= -(x+3)²+13. The axis of symmetry is just your a value equal to x, sometimes the answer can be equal to y value. But that is only if the whole equation is equal to x.
