Answer:
1. x^2y + 2xy - 15
When x=0 y=3
0^2(3) + 2(0)(3) - 15
0^2=0
0(3) = 0
0+2(0)(3)
0+2(0) = 0 + 0
0+0(3) = 0
0 - 15 = -15
1. -15
_______________________________________________
2. 2xy - 6x + 2y + 25
When x=0 y=3
2(0)(3) - 6(0) + 2(3) + 25
2(0) = 0
0(3) = 0
0-6(0) + 2 (3) + 25
-6(0) = 0
2(3) = 6
0-0 + 6 + 25
0 + 6 + 25
0+ 31 = 31
2. 31

3. x^2 y^2 + 2x - 2y + 15
When x=0 y=3
0^2 3^2 + 2(0) - 2(3) + 15
0^2 = 0
3^2 = 9
0*9=0
0+2(0) - 2(3) + 15
2(0)=0
2(3)=6
0+0-6+15
6+15 = 21
3. 21
