6. How do you solve the following equation:
Let’s Discuss
How do you solve the following equation:

7. Recall: Viral video problem

8. Find the Inverse

9. Recall: Part b. & c. of the Viral Video Problem
Part b. uses N(t) and
Part c. uses N (t) -1

10. In N(t), N(t) is 4 raised to the exponent t.
In the inverse,
N (t) is
the exponent of 4 to get t… -1

11. y=1 is not an exponential function.
