If the question meant f(x)=2^(x) -3 then the answer should be 1 over 4 or 1/4
X^2+2x-11=0, this would be the answer that you are looking for m8.
After striking a pair of arcs from each endpoint of a line segment, just join the intersection point of the 1st pair (above the segment) with the intersection point
of the 2nd pair (under the segment)
And this is how you construct the segment's perpendicular bisector
