If f(x)=4x−7 what is (a) f−1(5) (b) f−1(y) (Hint: what does x have to be to give an answer of 5, of y?) Enter N into a blank if there is no solution.

f−1(5)=

f−1(y)=

Respuesta :

well 5+5= 10 and if you multiplay that by 6 then you get 60 divide i by 2 and you get 30 and finally if you subtract that by 8 then you have 22. Hope this helps.
