Question

It is due today please help me.

Answer 1

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:

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

(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.
