Given:
f(x) = 1.5x²

Domain is all the values of x.
Range is all the values of y.

x y
1 f(1) = 1.5(1²) = 1.5(1) = 1.5
2 f(2) = 1.5(2²) = 1.5(4) = 6
3 f(3) = 1.5(3²) = 1.5(9) = 13.5
4 f(4) = 1.5(4²) = 1.5(16) = 24
5 f(5) = 1.5(5²) = 1.5(25) = 37.5

If we graph it, the following coordinates will be:
1st point (1,1.5)
2nd point (2,6)
3rd point (3,13.5)
4th point (4,24)
5th point (5,37.5)
so on...
