Which of the following is the closest approximation to e?

If a bacterium increases by 1% in 2 minutes, would this form an exponential curve?

What is the coordinate of intersection with the y-axis for y = e^x?

If an investment doubled every 3 years, would the growth of the investment form an exponential curve?

If y = 2^n, what is the value of y when n = 5?

If y = 5^n, what is the value of y when n = -3?

You are given that 6^a < 220 < 6^b and that 'a' and 'b' are consecutive integers. What are the values of 'a' and 'b'?

y = 9^x would cut the y-axis at the coordinate...
