A function is defined as a set of points for every x-value, there is only one y-value.
So, you can't have two y-values for every x-value.
Thus, (B) would be a relation, because x = 7 has two y-values, and as such, doesn't satisfy the condition of a function.
Since you want to put this in simplest form ... the easiest way you can do it is
3 (100) + 97
So, step 1] 3(100)= 300
Step 2] 300 + 97 = 397
Answer : 397 over 100

There's other ways too, but it'll take me all night to finish it
