Question

A heated piece of metal cools according to the function c(x) = (.5)x − 11, where x is measured in hours. A device is added that aids in cooling according to the function h(x) = −x − 3. What will be the temperature of the metal after five hours?

Answer 1

−8° Celsius

26° Celsius

32° Celsius

56° Celsius

Answer 2

the answers are shown above

Answer 3

You can see that the second function 'adds' additional cooling to your original function of cooling so you must add them both up and solve for x = 5 hours because "x is measured in hours."

Answer 4

c(x)+h(x) = ?
