Question

What is the axis of symmetry of the graph of `y = x^2-3x+9`?

Answer 1

`x = 3/2` or `1.5`

Explanation:

To find the axis of symmetry of a standard quadratic equation `(y = ax^2 + bx + c)`, we use the formula `x = (-b)/(2a)`.

We know that `a = 1` and `b = -3`, so let's plug them into the formula:
`x = (-(-3))/(2(1)) = 3/2`

Since the axis of symmetry is a line, it is `x = 3/2` or `1.5`.

Hope this helps!
