Question

Pauley graphs the change in temperature of a glass of hot tea over time. He sees that the function appears to decrease quickly at first, then decrease more slowly as time passes. Which statement best describes this function? NOTE: In the bottom right corner of each question, you will see an option to check answer.

It is linear because there is both an independent and dependent variable. It is linear because there is both an independent and dependent variable. It is linear because the graph decreases over time. It is linear because the graph decreases over time. It is nonlinear because linear functions increase or decrease at the same rate.

Answer 1

The statement that best describes the function is:

"It is nonlinear because linear functions increase or decrease at the same rate."

This is accurate because the description indicates that the temperature decreases quickly at first and then more slowly, which suggests a rate of change that is not constant—typical of a nonlinear function.
