I really need help can someone please answer?

The points (0,3), (1,8), (2,17), and (3,30) are on the graph of a function. Which of the following equations represents that function?
a.2x^{2}-3x+3
b.2x^{2}+3x-3
c.2x^{2}-3x-3
d.2x^{2}+3x+3

Answer:    D. 2x^{2}+3x+3    Step-by-step explanation:   Use the ordered pairs to determine the correct function   Point (0, 3)    x = 0 and y = 3- options A or D, the others result in y = -3    Point (1, 8)   x = 1, y = 8 - option A.   2*1^2 - 3*1 + 3 = 2 - incorrect    It leaves us with option D    2*1^2 +3*1 + 3 = 8 - correct    Check other two pairs as well:    2*2^2 + 3*2 + 3 = 17  2*3^2 + 3*3 + 3 = 30    This confirms option D is correct
