2 Answer

  • Answer is A.
    For a quadratic function, the rule at finding the points it to square the x value and then multiply by the coefficient to get the y.
    So.......
    X Y
    -2 2
    -1 .5
    0 0
    1 .5
    2 2

    And by looking at these points, A matches perfectly
  • I believe the correct graph for y = 1/2 x^2 is the first graph. To graph this equation, you must create an x,y chart. 
    Ex.) x , y
           -2, 2
           -1, 0.5
            0, 0
            1, 0.5
            2, 2
