Martina turns on a treadmill to start walking.
She takes 1 minute to gradually increase her speed and then walks at the same speed for 4 minutes. She increases her speed twice more during the 15 minutes she is on the treadmill, as shown on the graph below. Which best describes the function of Martina's walking speed over the interval (0, 15]?

Answer 1

Answer:

a peicewise function with seperate pieces of linear and step functions

Step-by-step explanation:

Answer 2

The statement that describes the function is: (a) a piecewise function with separate pieces of linear and step functions

From the attached graph, we have the following highlights

• The graph has several linear functions.
• The graph has multiple step functions, as well.

This means that: the function is best described by the given graph is statement (a)
