What's the equation of the axis of symmetry of the function f(x) = x2 + 8x - 10? A) x= 5
B) x= -4
O C) x=-5
OD) x= 4

x = -4

B is the answer

Step-by-step explanation:

To find the axis of symmetry, we will need to find the vertex of this function.

I have provided you with the steps to find the vertex.

After finding the vertex, pay attention to the x-value of the vertex because that is the axis of symmetry too. Hope this helps :)
