graph{(2/3)x^2 [-5, 5, -2.5, 2.5]}
Horizontal compression by 2/3

Explanation:

To graph, I would plug in values for x, I would use
-2,-1,0,1,2

The points you would get would be

  • (-2,8/3)
  • (-1,2/3)
  • (0,0)
  • (1,2/3)
  • (2,8/3)

Since there is a number in front of the x we know it affects the graph horizontally, either a compression or stretch
