What is the range of the function f (x) = + 6? f (x) > - 8 f (x) > - 6 f (x) > 6 f (x) > 8

We know that

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain

case a) f (x) = + 6

the range is 6

case b) f (x) > - 8

the range is the interval (-8, ∞)

case c) f (x) > - 6

the range is the interval (-6,∞)

case d) f (x) > 6

the range is the interval (6,∞)

case e) f (x) > 8

the range is the interval (8,∞)
