Grant is a member of a book club. he pays a $10 yearly membership fee and can purchase books through the club for $2.75 each. his total annual cost is a function of the number of books, b, that he purchases in a year: c(b) = 2.75b + 10 what is the total cost if he purchases 13 books in a year?

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

(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.
