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

Recall: Viral video problem

Find the Inverse

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

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
