The function f(x)= (x+3)^3is one-to-one. 1
a. Find an equation for f-'(x), the inverse function.
b. Verify that your equation is correct by showing that f(f- ?(x))
1
=x and f '(f())=x.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

126 maybe. sorry
