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 best describes this function? it is linear because the graph decreases over time. it is linear because there is both an independent and a dependent variable. it is nonlinear because linear functions are increasing functions. it is nonlinear because linear functions increase or decrease at the same rate.
Answer
Explanation:
Step1: Recall linear - function property
A linear function has a constant rate of change. That is, if (y = mx + b), the slope (m) is constant.
Step2: Analyze the given situation
The temperature of the hot - tea decreases quickly at first and then more slowly as time passes. So, the rate of change of the temperature (the slope of the function representing temperature vs. time) is not constant.
Step3: Determine the type of function
Since the rate of change is not constant, the function is nonlinear.
Answer:
It is nonlinear because linear functions increase or decrease at the same rate.
