Answer:
Second Option
[tex]y = 5[/tex]
Step-by-step explanation:
A constant function is one for which the range does not change regardless of the value of the domain.
[tex]f (x_1) = f (x_2) = f (x_3) = m[/tex]
Where m is a constant.
The constant functions are horizontal lines parallel to the axis of the x
Note that
[tex]y = x[/tex] is not a constant function because the value of y changes when x changes.
x = 1, y = 1
x = 2 y = 2
[tex]x = 5[/tex] is not a constant function because the range of the function is not constant. [tex]x = 5[/tex] is a vertical line
[tex]y = 5[/tex] is a constant function, since for any of the value of x, the value of y will always be 5
