The population P(t) of a culture of the bacterium Pseudomonas areuginosa is given by P(t) = -1700t^2 + 78,000t + 10,000, where (t) is the time in hours since the culture was started.

The time the culture was started was 88,000t

Step-by-step explanation:

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)
