Answer: The range of f(x) is
$f(x)\geq -2$

Explanation:

The given function is

f(x)+2=(1)/(6)|x-3|

It can be written as

f(x)=(1)/(6)|x-3|-2 ...(1)

The function is in the form of

g(x)=a|x-h|+k ...(2)

Where, a is scale factor and (h,k) is vertex of the graph.

On comparing (1) and (2), we get

a=(1)/(6)

h=3

k=-2

The value of a is
(1)/(6) . So, the graph compressed vertically. The value of a is positive, therefore the graph of f(x) opens upward.

We know the absolute value is always greater than or equal to 0.

$|x-3|\geq 0$

$(1)/(6)|x-3|\geq (1)/(6)(0)$

$(1)/(6)|x-3|\geq 0$

$(1)/(6)|x-3|-2\geq 0-2$

$f(x)\geq -2$

hope you've understood...
