Exponential functions! show work (if applicable)! 3 multiple choice questions! must do all 3, show work (if applicable), and answer correctly. otherwise, you will be reported, your answer will be deleted, and you will lose your points. if you have any questions or concerns, leave them in the comment section

3. For this one, I used an online graphing calculator to find which equation corresponds to the graph shown. 

The equation that I found to work was option A, which was f(x) = 8(1/2).

11. Each time one hour passes, the bacteria count approximately doubles, or comes out with a little less than it would be if it was doubled. 

After doubling the values three more times to get 8 hours, the option that was closest was C, 181,630.

12. Again, with this one I used an online graphing calculator to figure out which equation matched the values shown on the table. 

In doing this, I found that the one that matched best was option G, which is v(t) = 27,354(0.776). 

Hope this help!
