Answer :
Replace f(x) with x ( f(x) is really just y )
X=5y
Solve for y ( divide both sides by 5 )
X/5= y
^
^Fraction
Now, replace y with f^-1. (-1 is an exponent ; f^-1 just indicates that this function is an inverse.)
F^-1 = x/5
Final answer^
X=5y
Solve for y ( divide both sides by 5 )
X/5= y

^Fraction
Now, replace y with f^-1. (-1 is an exponent ; f^-1 just indicates that this function is an inverse.)
F^-1 = x/5
