Transcribed Image Text: Assume the velocity of a person traveling along a straight hiking trail is given by the
graph depicted. The input to the function is time in hours, and the output is velocity
in miles per hour. The trail travels east-west, and the velocity shown is the eastward
velocity.
Below you will state when the hiker’s acceleration was positive, negative and zero. If
the time is an interval give the interval in the form (a, b) or if there are multiple
intervals then list the intervals with commas between them like (a, b), (c, d). If the
times are a series of single values give the values as a, b, c… List values from smallest
to largest.
For the time interval (0, 10), state the times when the acceleration of the hiker is
positive.
State the times when the acceleration of the hiker
is negative.
State the times when the acceleration of the hiker is
zero. Transcribed Image Text: -4
