Question

number 10, only the answer is x+2 over 8. but idk how you get that answer

In Problems 10 - 13, find the inverse of the given function (or state why the function has no inverse 10. f(3) = 8x - 2 11. 9(x) = 23 - 2

Answer 1

Inverse (lo) &a-2 fo) in) = On - 2 = y n to a) is mapping to y. If a fonetion f(n) is Then inverse fonction f(n) maks y back to a. an * Interchanging y by-2 = n => for solving Now nt 2 88 키 at2 8 - x+2 y => flu) = 00+

(11) 23_2 En) = n3 - 2 = > y to > If a fonction f(n) is mapping y then inverse fonction f(n) maks y back to re. an * Interchanging y n 43-2 - y solving for y Now y3 = n+2 35ntz 9 f(n) Inverse = nt2
Please give it a thumbs up if you like the answer. Comment if any problem in solution. :)
