If f(x)=2x+1/x Find f^-1(x)
Masteriza [31]

Answer:

• Let f(x) be m

m =  \frac{2x + 1}{x}  \\  \\ mx = 2x + 1 \\  \\ mx - 2x = 1 \\  \\ x(m - 2) = 1 \\  \\ x =  \frac{1}{m - 2}

Therefore:

{ \boxed{ {f}^{ - 1} (x) =  \frac{1}{x - 2} }} \\

If a number is divided by a negative number will the outcome be positive?
Zielflug [23.3K]
That would depend...

-4 / -2 = 2........4 / 2 = 2 <== if the signs are the same
but
4 / -2 = -2.......-4 / 2 = -2 <== if the signs are different

 So basically, if the signs are the same, the result is positive and if the signs are different, the result is negative
