#1

A 12-inch candle begins to burn at a constant rate. The function that models the height, h, in inches of the candle after t minutes is given by this equation. Enter your answers in the boxes.

h(t)=−15t+12

The domain of h is the set of real numbers that are greater than or equal to and less than or equal to .

The range of h is the set of real numbers that are greater than or equal to and less than or equal to .

Answer:

Range of h is the closed set [0,12] i.e., 0≤ h ≤ 12.
Domain of h is the closed set [0,4/5] i.e., 0 ≤ t ≤ 4/5
