We know that The range<span> of a function is the complete set of all possible </span>resulting values<span> of the dependent variable (</span><span>y, </span><span>usually), after we have substituted the domain</span>
case a) <span>f(x) = + 6 the range is 6
case b) </span><span>f(x) > –8 the range is the interval (-8,</span>∞)
case c) <span>f(x) > –6 </span>the range is the interval (-6,∞)
case d) <span>f(x) > 6 </span>the range is the interval (6,∞)
case e) <span>f(x) > 8 </span>the range is the interval (8,∞)
