#1

  • (1,1) and a=5

y=ax²

  • y=5(1)²
  • y=5

Coordinates (1,5)

#2

  • (5,25) and a=-0.6

So

  • y=-0.6(5)²
  • y=-0.6(25)
  • y=-15

Coordinates (5,-15)

#3

  • (-2,4) and a=-3

So

  • y=-3(-2)²
  • y=-3(4)
  • y=-12

Coordinates (-2,-12)

#4

  • (-4,16) and a=1/2

So

  • y=1/2(-4)²
  • y=16/2
  • y=8

Coordinates (-4,8)
