Input (x) 5 6 7 8 Output (y ) 2 5 8 11 Part A: Do the data in this table represent a function? How do you know? (3 points) Part B: Compare the data in the table with the relation f(x) = 2x + 16. Which relation has a greater value when x = 5, the table or the equation? (2 points) Part C: Using the relation in Part B, what is the value of x if f(x) = 92? Show your work. (5 points)

Element x decays radioactively with a half life of 8 minutes. if there are 450 grams of element x, how long, to the nearest tenth of a minute, would it take the element to decay to 37 grams?
