Answer:
The value of y is 5.
Step-by-step explanation:
Given function is,
y = ⌊x⌋,
Which is a greatest integer function,
Since, the greatest integer function is a piece-wise defined function, that gives an integer value, also, If the number is not an integer, we use the next smaller integer.
Thus, ⌊5.7⌋ = ⌊5+ 0.7⌋ = 5,
Hence, when x = 5.7 ,
y = ⌊5.7⌋ = 5,
