Question 51184
The way to find an inverse function, you begin with an xy equation:{{{y = 7x^5 - 3}}}.


There are two steps:  
1.  Interchange the x and y; and 
2.  Solve for y.


Given:  {{{y = 7x^5 - 3}}}


Step 1:  {{{x= 7y^5-3}}}


Step 2:   Solve for y.
Add +3 to each side:{{{x+3= 7y^5}}}


Divide by 7:  {{{(x+3)/7=y^5}}}


Take the 5th root of each side or raise both sides of the equation to the {{{1/5}}} power
  {{{ ((x+3)/7)^(1/5) =y }}}


It looks like e) is the correct answer!
