Work Step by Step
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 \[\left\{ x|0\le x\le 5 \right\}\]
