The function $f ( x ) = x ^ { 2 }$ is defined on the set of real numbers. For real numbers in the interval $[-3, 3]$, the graph of $y = f(x)$ is given in the coordinate plane divided into unit squares as shown in the figure. In the unit squares divided by this graph; the regions below the graph are colored blue, and the regions above are colored yellow as shown in the figure. Accordingly, what is the ratio of the sum of the areas of the blue regions to the sum of the areas of the yellow regions?\ A) $\frac { 2 } { 3 }$\ B) $\frac { 3 } { 4 }$\ C) $\frac { 4 } { 5 }$\ D) $\frac { 5 } { 6 }$\ E) $\frac { 6 } { 7 }$
