(Answer ID # 0663048)
State for each of the following relations whether y is a function of x.

1.   y =    -11 - 15x	2.   14 + 10x2 = 7y2	3.   86 = 6y2 + 11x2
4.   10 = x2 + y - 1	5.   4y2 = 12 - 10x2	6.   14y2 + 14 = x
7.   6 = x2 + 1 - y	8.   -3x2 = -8y	9.   -11x3 + 12 = y
10.   -14x2 + y - x = -14x2 - 40	11.   x = |-15y - 11|	12.   -13 - 12y3 = x
13.   x = |-13y - 15|	14.   50 = -3y2 - 14x2	15.   4 = -x2 - y - 1
16.   -4y = -5x2	17.   -14y3 - 15 = x	18.   12x3 + 15 = y
19.   -10 + 14x2 = 2y2	20.   -6y2 = 13 - 10x2	21.   10 = -1 + x2 + y
