Answer :
The given function is Y = 6
The output will be always 6 for any input
So, when input = 1 , output = 6
when input = 7 , output = 6
when input = -3 , output = 6
when input = -5 , output = 6
The function at this time is called a constant function
It will be a horizontal line parallel to x-axis at y = 6
