Given the function f(x)=0.3(4)x what is the value of f−1(6)
a. 0.360 b. 1.242 c. 2.161 d. 2.312
Answers
For this case we have the following function: Rewriting we have: From here, we clear the value of x: Rewriting we have: Therefore, the inverse function is given by: For x = 6 we have: Answer: is the value of f^-1(6) is: c. 2.161
f(x)=0.3(4)^x
f^-1(x) = ?
x = 0.3(4)^y
4^y = x/0.3
4^y = 6/0.3
4^y = 20
y = 2.161
