Question
Results of the INT functions are shown in the spreadsheet.
If f(x) = INT(x), what is f(4.6), f(5) and f(-6.5) ?
- 5 , 5 and -6.5
- 4.6 , 5 and -6.5
- 4, 5 and -7
- 5 , 5 and -6
Hint:
The floor function returns the largest nearest integer which is less than or equal to a specified value.
The correct answer is: 4, 5 and -7
Observing the values in the table, we can say that f(x) = floor(x).
Floor(4.6) = 4
Floor(5) = 5
Floor(-6.5) = -7
Notice the trend of the function values and identify the function which is used.
