The graph shows a predicted population as a function of time.

Choose the one statement below that is true about this graph.


A. The initial population was more than 500.


B. The graph shows the population decreasing without bound.


C. The graph has an x-intercept and a y-intercept.


D. The graph shows quadrant III because only negative values make sense for this situation.


E. Based on the graph, it is predicted that it will take more than 3 years for the population to be greater than 500.

Answer 1

Okay: so based on deductive reasoning what can you conclude about this graph?

Answer 2

One, it's increasing and up to 5000 on the y axis.

Answer 3

Well... it definitely looks like an exponential function so we can say the function is increasing without bounds.

Which means: B is definitely false.

What else can you conclude about the graph by looking at it?

Answer 4

Well, I'm thinking D could be marked out maybe?

Answer 5

And C?

Answer 6

I think the answer is E.
