the graphs of two functions f(x) and g(x) intersect only twice. Selected value of the functions are shown in the table below. Based on the table, state the solutions to the equation: f(x) = g(x)

Set $r$ is a set of rectangles such that (1) only the grid points shown here are used as vertices, (2) all sides are vertical or horizontal and (3) no two rectangles in the set are congruent. if $r$ contains the maximum possible number of rectangles given these conditions, what fraction of the rectangles in set $r$ are squares? express your answer as a common fraction.
