Danielle walked from her house to several locations in her town. the graph represents her distance from home after x hours.

a. how far from home was danielle after 1/2 hour?

b. what was danielle's speed between 0 and 1 hour?

c. what was danielle's speed between 1 and 2 hours?

d. what is the domain when the function is increasing?

e. what is the domain when the function is decreasing?

f. what is the domain when the function is constant?

!

According to the graph, after half hour, Danielle was 1 mile far from home.

To find the speed we have to apply the formula:

From and , Danielle went from to  . Replacing this values, we calculate the speed:

Therefore, the speed between 0 and 1 hour is 2 miles per hour.

The Danielle's speed between 1 and 2 hours is zero (). Because, according to the graph, during this time, Danielle didn't move, and without move, there's no speed.

The domain when the function is increasing refers to the increasing x intervals.

From the graph, this increasing interval is from 0 to 1 hours only, it's the only period of time when Danielle was increasing her position.

The parts of the decreasing domain are:

In the graph, you can see these decreasing intervals, which are characterized by a downwards direction of the line.

The parts where the function is constant:

Constant intervals, means no increase, no decrease, just an horizontal line.

answer: the anser is 3
