Answer:
x = 3
Step-by-step explanation:
The standard form of a parabola (x^2 function) is:
If we algebraically manipulate this, we can have the vertex form:
Where
x = h will be the axis of symmetry
k will be the vertical shift
(h,k) would be the vertex
Now, the function given in this problem is given in vertex form:
From the original vertex form, we can say that this equation has the folllowing variable values:
a = 1
(3,4) is the vertex
x = 3 is the axis of symmetry
4 is the vertical shift
We are concerned with axis of symmetry. Thus, we can see that
x = 3 is the axis of symmetry
