Question

Find x when f(x)=1 . (These means find the input that gives an output of 1.) f(x)=1/x-2

Answer 1

Given function is f(x) = $\frac{1}{x}-2$

Value of f(x) is the output value when we place the value of 'x' (input value) in the given function.

If the output value of f(x) = 1,

1 = $\frac{1}{x}-2$

1 + 2 = $\frac{1}{x}$

$\frac{1}{x}=3$

$x=\frac{1}{3}$

Therefore, for the input value x = $\frac{1}{3}$, output value of the function is 1.
