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
