Question
Draw the graph of the Greatest Integer Function.
✓
Answer
The greatest integer function is denoted by y = [x], For all real number, x, the greatest integer function returns the largest integer less than or equal to X.
| Value of x | f(x) = [x] |
 | |
| $-3 \leq x<-2$ | -3 |
| $2 < x<-1$ | -2 |
| $-1 \leq x<0$ | -1 |
| $0 \leq x<1$ | 0 |
| $1 \leq x<2$ | 1 |
| $2 \leq x<3$ | 2 |
| $3 \leq x<4$ | 3 |
