The following graph shows three different exponential growth or decay functions. Each graph has a y-intercept of 8. One function shows the exponential growth of a bacteria that has a growth rate of 0.06, in thousands. Another function shows a 2% increase in the population of a species, in thousands. The third function shows a chemical compound, in thousands of grams, with a half-life of about 11.55 years. What graph represents each situation? What is the population or mass of the item in 10
years? What is the equation for each function?

the equations will all look like y=8e^(r*t)
