Nina graphs the function y=⌊x⌋ to learn the properties of the parent floor function.

What is the value of y when x=5.7?

5
5.50
5.75
6

The value of y when x=5.7 is 5.

This is because the floor function ⌊x⌋ rounds down to the nearest whole number, so when x=5.7, the nearest whole number below 5.7 is 5.
