Question

Suppose Joyce jogs for only 20 minutes. How does the function's domain and range change?

A) The domain remains the same, but the range decreases.
B) The domain decreases, but the range remains the same.
C) Both the domain and range remain the same.
D) Both the domain and range decrease.

Answer 1

When Joyce jogs for only 20 minutes, the domain of the function changes, but the range remains the same.

Step-by-step explanation:

When Joyce jogs for only 20 minutes, the domain of the function changes. The domain is the set of input values, in this case, the time Joyce jogs. So, if Joyce only jogs for 20 minutes, the domain would be all real numbers from 0 to 20 inclusive. However, the range of the function remains the same. The range is the set of output values, in this case, the distance Joyce jogs. The range would still be all real numbers.

So, the correct answer is A) The domain remains the same, but the range decreases.
