a candle 6 inches high burns at a rate of 1 inch every 2 hours for
5 hours. (use interval notation for the domain and range of the
function that models this situation.)
the candles burning rate is
in./h.
the candles height h (in inches) at any time
t (in hours) is modeled by h(t) =
since the candle burns for 5 hours, the domain is restricted to the
intervalo,
the range is
