Not sure if this is logically correct:
The vertex（middle point) of a Quadratic equation of one variable
equals to
-b/2a，[（4ac-b 2）/4a]
Since John get a and b correct, means the x axis value of John is the same as the corrected function
Meanwhile, c means the intercept cordinate of the function to the y axis when x equals to 0,
While Kaite get c correct, means the y axis value for vertex（middle point) is the same as the corrected function
So just simply move Katie function drawing to the corrected X axis value,
and simply added number from the middle point: 4+3 =7; 4 -3 = 1
