Answer to Problem 9PPS
Nonlinear
No
No Symmetry
Positive for all real numbers.
The function is not negative
The function increasing for
The function is decreasing for
Relative Extrema:
End Behavior:
Explanation of Solution
Given: Identify the function graphed as linear or nonlinear. Then estimate and interpret the intercepts of the graph, any symmetry, where the function is symmetry, where the function is positive and negative, increasing or decreasing, the
Linear or Nonlinear: Since the graph is a curve, not a line. The graph is Nonlinear.
This means there is no medicine in blood when we start measuring.
Symmetry: The graph does not have line symmetry.
Positive: The graph is positive when it is above the
This means that the after taking the medicine there is always some amount of medicine in blood.
Negative: The graph is not negative
Increasing: The graph is rising from left to right so it is increasing for
This means that the concentration of medicine increases after first
Decreasing: The function is decreasing for
This means that the after eight hours the concentration of the medicine decreases.
Relative Extrema:The relative maximum is about
End Behavior: As
This means that concentration of medicine become less as the time goes, until there is none left in the blood.
