Suppose one painter can paint the entire house in ten hours, and the second painter takes seven hours. Approximately how long would it take the two painters together to paint the house? 3 hours and 45 minutes
4 hours and 7 minutes
3 hours and 15 minutes
4 hours and 12 minutes

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

(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.
