If there was a coordinate pair (1,7) and was added to a set of {(-2,6) (0,5) (1,-4) (3,5) and (6,4)}, why would the variable y no longer be a function of the variable x?

the infinity sign

step-by-step explanation:

8y^50

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
