Answer:

Graph C with values below

Explanation:
To do this you substitute x with the values of x given to solve for y:
-3:

  • y=
    (1)/(2)(-3)³-2(-3)+1
  • y= (
    (1)/(2)×-27)+6+1
  • y= -13.5+7
  • y= -6.5

-2:

  • y=
    (1)/(2)(-2)³-2(-2)+1
  • y= (
    (1)/(2)×-8)+4+1
  • y= -4+5
  • y= 1

0:

  • y=
    (1)/(2)(0)³-2(0)+1
  • y = 0+0+1
  • y= 1

2:

  • y=
    (1)/(2)(2)³-2(2)+1
  • y= (
    (1)/(2)×8)-4+1
  • y= 4-4+1
  • y=1

Using these values we can fill out the table and see the It must be graph C that is the correct curve.
