I maybe totally wrong but i want to say either A or C. A nonreal number is any number that when multiplied by itseld produces a negative number.
3 and 1 half is also known as 3.5,
3.5 x 3.5 = 12.25
in fractions that is 12 and 1 quarter
Multiply first
100x50=5000
5000-32=4968
The y intercept is 4, and the x intercept is 0.
