Question

What is the axis of symmetry for this function?
y=x2 - 2x - 3
.

Answer 1

That will be 1 :)))))))))))))))

Answer 2

x=1

Explanation:

You can find the axis of symmetry from the equation of a function by using the formula x= -b / 2a ( ax^2 + bx + c).

In this particular function, you can see that b is 1 and c is -3.

x= -b / 2a

x= - (-2) / 2(1)

x= 2 / 1

x= 1
