QuestionIdentify the linear function among these equations: $f(x)=5-\frac{3}{x}$, $f(x)=3x-\frac{2}{5}$, $f(x)=4x-\frac{5}{2x}$, $f(x)=|x-4+3|$.

Studdy Solution
After examining all the given equations, we find that the second equation $f(x)=3x-\frac{2}{5}$ is the only one that represents a linear function.
So, the equation that represents a linear function is $f(x)=3x-\frac{2}{5}$.
