You can put this solution on YOUR website! Because the graph extends "all the way" to the left and "all the way" to the right, the domain (set of all x values) is all real numbers.
Because the graph extends "all the way" up and "all the way" down, the range (set of all y values) is also all real numbers.
You can put this solution on YOUR website! Use the permutations formula
nPr = n!/(n-r)!
5P3 = 5!/(5-3)!
= 5!/2!
= 5x4x3x2x1 / 2x1
= 5x4x3
= 60
The Number counting principle can also be applied, but its the same thing really.
