Answer:
30/1
Step-by-step explanation:
Max can read 60 pages per 2 hours. To get how many pages he can read per hour you divide 60 by 2, which is 30. 30 in fraction form is 30 over 1.
Let f(x) = y
y = 2^x
x = 2^y
Solve for y.
ln x = ln(2^y)
ln x = y ln 2
ln x/ln 2 = y
Replace y with f^(-1) x.
f^(-1) x = ln x/ln 2
We now know f(x) and f^(-1) x.
Use your graphing calculator to graph the function and its inverse on the same xy-plane. If you don't have a graphing calculator, use DESMOS online.
Good luck.
