The expression | 20-31 | gives us the distance between the numbers 20-31. write a similar equation for the distance between -5 and -15 and simplify it

10

Step-by-step explanation:

Either | -5 - (-15) | or | -15 - (-5) |.  The end result is 10.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
