A.4.3.3 Boiling Water

The function W gives the temperature, in degrees Fahrenheit, of a pot of water on a stove, t minutes after the stove is turned on. Explain the meaning of each statement. a. W(0) = 72 b. W(5) > W(2) c. W(10) = 212 d. W(12) = W(10) e. W(15) > W(30) f. W(0) < W(30)

Sketch a possible graph of function W. a. W(0) = 72 b. W(5) > W(2) c. W(10) = 212 d. W(12) = W(10) e. W(15) > W(30) f. W(0) < W(30)

Why might it be true that W(15)>W(30)?
