what's the inverse of y=8x-5?
-------------------------------------------------------
answers:
Krishnamurthy say: inverse function y(x) = 8 x - 5
(y + 5) / 8
-
khalil say: y=8x-5
x = (y + 5) /8
x → y and y → x
y = ( x + 5) / 8
-
TomV say: y = f(x) = 8x-5
g(x) = f^-1(x)
f(g(x)) = x = 8g(x)-5
g(x) = f^-1(x) = (x+5)/8
Ans: f^-1(x) = (x+5)/8

Morningfox say: Inverse of y = 8x -5 is done this way:
(1) Add 5 to each side
y + 5 = 8x
(2) Divide each side by 8
y/8 + 5/8 = x
(3) Change the "y" to "x" and"x" to "y"
x/8 + 5/8 = y
Done!
