An architect is designing an office building with n floors that will have an FM radio antenna 15.85 meters tall on its roof. Each floor of the building will be 3.9 meters high. Which function can be used to find the total height of the building in meters, including the FM antenna?

• h(n) = 15.85n + 3.9

• h(n) = 3.9n + 15.85

• h(n) = 3.9n - 15.85

• h(n) = 19.75n

What is the range of the function shown?

• {-7, -2, 0, 5}

• {-9, -4, -1}

• {-9, -7, -4, -2, -1, 0, 5}

• {-1}
