8x-7x> 14-8

x> 6

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

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:

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

p = 6s
