Suppose that the functions q and r are defined as follows. q (x) = 2x+2
r(x) = x² +1
Find the following.
(r •q)(-3) = 0
(q •r)(-3) = 0

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
