Answer:
(a) The range of the function represents the set of values on the y-axis. We see that function has an absolute maximum, then the range of the function is:
[tex]Ran\{f(x)\} = (-\infty, 4][/tex]
(b) The location of the maximum is represented by its ordered pair. After direct observation, we located this maximum at [tex](x, f(x)) = (-1.3, 4)[/tex]
(c) By direct observation we find that the value of [tex]y[/tex] when [tex]x = 1.5[/tex] is -12.
(d) By direct observation we conclude that the values of [tex]x[/tex] when [tex]y = -20[/tex] are -4.8 and 2.
