3.} Suppose we have a cup of ice water whose temperature in Fahrenheit T0) after t minutes can be modeled by the following equation: T0) = 70 508 '0'\" a.) Draw a sketch of the function. b.) What is the horizontal asymptote ofthis function? Explain what it means in this context. c.) What will be the temperature of the ice water after 20 minutes? Show your work. d.) At what time will the ice melt? Note: The melting point of ice is 32F? Show your work
