sqrt%284x%5E2-4x%2B1+%29=+2x+-+1


4 largest integer values of 2x-1 for which this equality is not true will be four integers and they are:
2x-1=0
2x=1
x=1%2F2......first solution for which this equality is true
4 largest integer les than x=1%2F2 are:
x=0,-1,-2,-3
the average of the 4 largest integer values:%280%2B%28-1%29%2B%28-2%29%2B%28-3%29%29%2F4=-1.5=>-11%2F2

answer: A)-1+1%2F2
