The graph shows the amount of a chemical in a water sample. It is decreasing exponentially.
Find the coordinates of the points labeled A.
The graph shows the amount of a chemical in a water sample. It is decreasing exponentially.
Now find the coordinates of point B.
The graphs shows the amount of a chemical in a water sample at different times after it was first measured.
Select all statements that are true.
The graph shows the amount of a chemical in a patient's body at different times measured in hours since the levels were first checked.
Could the amount of this chemical in the patient be decaying exponentially? Yes or No and back it up.
The height of a plant in mm is 7. It doubles each week. Select all expressions that represent the height of the plant, in mm, after 4 weeks.
The question is not asking what is happening, as we already know it doubles. What is happening to the DIFFERENCES in the values?
Yes, by factor it means the growth factor.
