question 23

Multiple Choice

In the following figure, f(t) gives the population P​₁ of a certain bacteria culture at time t after a portion of bactericide A was introduced into the population at t = 0. The graph of g gives the population P​₂ of a similar bacteria culture at time t after a portion of bactericide B was introduced into the population at t = 0. ​ ​
Which population is decreasing faster at t​₁ and at t​₂?
​

• A) The populations are decreasing at the same rate at t​₁, P​₂ is decreasing faster at ​t​₂
• B) ​P​₁ is decreasing faster at t​₁, the populations are decreasing at the same rate at t​₂
• C) ​P​₂ is decreasing faster at t​₁, ​P​1 is decreasing faster at t​₂
• D) P₁ is decreasing faster at t​₁, ​P​₂ is decreasing faster at t​₂
