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

Answer:
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 :)
