Question

The graph shows the temperature over a period of time of a chemical compound that is placed in a cold chamber. What is the domain of this function? Graph showing a line segment that goes from ordered pairs 0, 20 to 35, negative 10

Answer 1

Answer:

Option C

Step-by-step explanation:

Since the graph shows the temperature over a period of time of a chemical compound that is placed in a cold chamber, our aim is to find what is the domain of this function.

We know that the line graph shows the temperature over a period of time.

All inputs that are able to appear is the domain for the definition of each function.

Imagine the function goes from (x1, y1) to (x2, y2), then we can conclude that its set of coming values, D, is [x1, x2].

We have that our points are (0,20) and (35,10). This lets us know and conclude that lines segment joining these two points.

Hence, its function domain is equal to [0, 35].
