Please help and show working outs of the screenshot attached

Hey, do you know how to screenshot images? There is also a website for if needed

Step-by-step explanation:

(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.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
