You are growing hydrangeas in your garden. The flowers of the hydrangea plant can take different colors (pink or blue) depending on the acidity of the soil. You don't care which colo you get, but you do want healthy hydrangeas. A certain type of bacteria grows in your area an these bacteria are not good for the hydrangeas. You perform an experiment to see which type soil you should use to grow hydrangeas by analyzing bacterial growth in neutral soil and acid soil. You determine that the size of the bacterial colony over time can be modeled by the following functions: Colony in neutral soil: y=- 21+1 120 1+1 41+3 Colony in acidic soil: = 72 + 3 120 Where y represents the population, in thousands, after / hours. (a) How many bacteria did you start off with in each type of soil?(b) Which type of soil should you use for planting your hydrangeas? Explain and justify your solution
