It says to write a piecewise function for the graph.

y = 2x/3 + 0 for x < 0

y = -3x for x ≥ 0

Step-by-step explanation:

Blue line

line rises 2 units for each 3 units of run so slope is 2/3, intercept is 2

y = 2x/3 + 0 for x < 0

Red line

line falls 3 units for each 1 unit of run so slope is -3, y intercept is 0

y = -3x

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
