Question 1080004
Tip: DO NOT POST MORE THAN ONE QUESTION PER POST OR YOUR PROBLEMS WILL BE IGNORED. 



I will do question 1 only. 



f(x) = 2x + 1



Let f(x) = y



y = 2x + 1



Switch y with x.



x = 2y + 1



Solve for y.



x - 1 = 2y



(x - 1)/2 = y



Replace y with the inverse function notation.



(x - 1)/2 = f^(-1) x



Do the rest in similar fashion.
