Answer:

B. x=1

Step-by-step explanation:

Let us define axis of symmetry first.

The point right in between the two x-intercepts of a quadratic equation is called axis of symmetry.

We have x-intercepts of -3 and 5

In ordered to find the axis of symmetry we have to find their middle intercept

To find the axis of symmetry:

[tex]= \frac{-3+5}{2}\\=\frac{2}{2}\\ =1[/tex]

So the axis of symmetry is x = 1 ..
