The x-intercepts of a quadratic function are −3 and 5. What is the equation of its axis of symmetry?

x = −3
x = 1
x = 5
x = −15

help please will give brainliest

x = 1

Step-by-step explanation:

The graph intersects the x-axis at -3 and 5.  The axis of symmetry is precisely halfway between these two points:  (-3 + 5) / 2 = 2 / 2 = 1.

The axis of symmetry is the vertical line x = 1.

the answer is 62
