1. Find the inverse of g(x)=2x-1 / 3x+4


Sagot :

Answer:

Replace x by y and y by x then solve for y:

Replace x by y and y by x then solve for y:x = (2y +1)/(3y - 4) —-> x(3y-4) = 2y + 1 → 3xy -4x = 2y +1 —->

Replace x by y and y by x then solve for y:x = (2y +1)/(3y - 4) —-> x(3y-4) = 2y + 1 → 3xy -4x = 2y +1 —->y[3x -2] = 4x +1 —→ y = (4x+1)/(3x-2) =f^-1 (x).
