Which of the following represents a function? a. (5,1), (5,2), (5,3), (5,4)

c. (-5,6), (-5,6), (-5,6), (-5,6)
d. (8,3), (8,3), (-8,-3), (-8,-3)

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240
