Find the inverse of fx 1 x 43 x 5 show work step by step a
Find the inverse of f(x) = (-1 x + 4)/(-3 x -5)
show work step by step and explain
Solution
f(x) = (-x +4)/( -3x -5)
y = (-x +4)/( -3x -5)
To find inverse : replace x= y and y =x
So, x = ( -y +4)/(-3y -5)
-3xy -5x = -y +4
y ( -3x +1) = 4+5x
y = (4 +5x)/(1 -3x)
So, f^-1(x) = (4 +5x)/(1 -3x)
