What are 3 points if the x-coordinate is square of the y-coordinate?
:
That means:
x = y^2
or
y^2 = x
:
Find the square root of both sides:
y =
:
Choose 3 values of x and find y (all have to be positive)
x | y
------
1 | 1
4 | 2
9 | 3
:
AS an example: find y when x = 9
y =
y =
y = 3
:
Since you can choose the x values, choose perfect squares.
