To clarify the expression f(x) = 1 x, we interpret it as f(x) = 1 imes x. In this case, it means that the function f evaluates to the value of x when multiplied by 1. Since multiplying any number by 1 yields the same number, we can conclude that:
f(x) = 1 imes x = x.
Thus, the equivalent value of f(x), when f(x) = 1 x, simplifies down to just x.
In summary, if f(x) is defined as 1 x, then f(x) is equivalent to x.
