Question

It is due today please help me.

Answer 1

(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:

`Ran\{f(x)\} = (-\infty, 4]`

(b) The location of the maximum is represented by its ordered pair. After direct observation, we located this maximum at
`(x, f(x)) = (-1.3, 4)`

(c) By direct observation we find that the value of
`y` when
`x = 1.5` is -12.

(d) By direct observation we conclude that the values of
`x` when
`y = -20` are -4.8 and 2.
