Monica did an experiment to compare two method of warming an object. The results are shown in the table above. Which statement best describes her results?

• The temperature using both methods changed at a constant rate.

• The temperature using both methods changed at an exponential rate.

• The temperature using Method 2 changed at a constant rate.

• The temperature using Method 2 changed at an exponential rate.

Monica did an experiment to compare two method of warming an object. The results are shown in the table above. Over time, which method will exceed the other? How do you know this?

• Method 2 because linear growth always beats exponential growth over time.

• Method 1 because linear growth always beats exponential growth over time.

• Method 2 because exponential growth always beats linear growth over time.

• Method 1 because exponential growth always beats linear growth over time.
