$\left\{ x|0\le x\le 5 \right\}$
From the given graph, it is clearly evident that for the first five years of relationship , Passion is greater than or equal to Intimacy after which Passion is less than Intimacy. Let x represent number of years. Then the number the inequality that would satisfy the provided condition would be, $0\le x\le 5$ This can be represented in set builder form as: $\left\{ x|0\le x\le 5 \right\}$ Number of years that satisfy the desired condition in set builder form is $\left\{ x|0\le x\le 5 \right\}$
