Based on the scatterplot and computer output, a A popular social media platform has begun offering stock shares to the public. In the past 2 years, the reasonable estimate for the stock price for week 95 is: price of the stock has generally increased.

Find a graph or bar chart that represents a real situation where you could use a linear or exponential equation to model the data. Identify the type of function that is being modeled and why you believe it to be this type. Estimate the equation for the function.
9. A certain bacteria population triples each minute. Suppose you begin with a single bacteria cell. a. Create a table of values to show the population of bacteria at the end of each minute for the first 5 minutes of growth. b. Graph the data from your table using the desmos graphing calculator. (insert below). c. Is the population of bacteria growing linearly or exponentially? Explain.
A population numbers 20,000 organisms initially and decreases by 3% each year. Suppose P represents population, and t the number of years of growth. Write an exponential model to represent this situation. P = Preview
