The domain is x in RR. The range is y in [5, +oo)

Explanation:

The function is

y=|x|+5

For the absolute value, x can take any value.

Therefore, the domain is x in RR

The minimum value of y is when x=0

=>, y=5

And due to the presence of the asolute value, y can take only positive values as

|-x|=x

Therefore, the range is y in [5, +oo)

graph{|x|+5 [-56.73, 60.37, -20.6, 37.95]}
