14. The statement f (4) = 20 tells us that W = 20 when t = 4. In other words, in 2019, Argentina produced 20 million

15. (a) If we consider the equation

C = 4T − 160

simply as a mathematical relationship between two variables C and T , any T value is possible. However, if we t

hink of it as a relationship between cricket chirps and temperature, then C cannot be less than 0. Since C =
pn pn pn pn pn pn pn pn pn pn pn pn pn pn pn pn pn pn pn p n


pn0 leads to 0 = 4T − 160, and so T = 40 F, we see that T cannot be less than 40 F. In addition, we are t

Domain = All T values between 40 F and 134 F

(b) Again, if we consider C = 4T − 160 simply as a mathematical relationship, its range is all real C values. Howe
