The length of the base is 32.6
3.3 + 3.3 = 6.6
Subtract 6.6 from 71.8 : 65.2
Divide that by 2 : 32.6
You multiply by 10 or more
It would be the first one (x,-y) because say for example you take the point of v1 (4,-1) and reflect across x axis you get (4,1) for v
The vertex of the parabola is <span><span>(<span>2,1</span>)</span><span>(<span>2,1</span>)</span></span>
.
So, the axis of symmetry is the line <span><span>x=2</span><span>x=2</span></span>
.
