3. The average temperature of the planet is expected to rise at an average rate of 0.04 degrees Celsius per year due to global warming. The average temperature in the year 2000 was 14.71 degrees Celsius. The average
Celsius temperature, C, is given by C=14.71+0.04x, where x represents the number of years since 2000.
