Answer:
the equation which shows the temperature over time is:
y(t)= -7+3t
Step-by-step explanation:
We are given that:
On a very cold morning, it was -7°F. As the day went on, the temperature rose 3 degrees each hour.
We are asked to find the equation which shows the temperature over time
Let y be the temperature and t be the time
clearly, y depends on t
and y at t=0 is -7
y(t)= -7+3t
Hence, the equation which shows the temperature over time is:
y(t)= -7+3t
