If n > 0 , which of the following must be true? i n² > 1 ii n - n² < 0 iii 2n - 1 > 0
a. i only
b. ii only
c. iii only
d. i and ii only
e. none

E. none because, pretend n=.1, then .1² is .01 which is less than 1, so then I isn't always true. .1-.1² is .09 which is greater than zero, so II isn't always true. Lastly, 2(.1)-1=-.8 which is less than zero, so III isn't always true
