Let f(x)=5x+12.find f-^1(x) a.12x+5 b.1/5x+12 c.5/x-12 d. x-12/5

For this case we have the following function:
 
 Rewriting the function we have:
 
 From here, we clear the value of x.
 We have then:
 
 
 Then, we return the change of variables.
 We have then:
 
 Rewriting, we have that the inverse function is:
 
 
 D.x-12/5

That is so true, i can’t believe how true this is

Use a calculator basically
