Math Problem Statement

f(x) = \begin{cases} \dfrac{5}{x} & \text{for} ~~~~x\gt{5} \ x-4& \text{for} ~~~~ x \leq5\end{cases}

Solution

The given function is a piecewise function, which is defined as:

\begin{cases} \dfrac{5}{x} & \text{for } x > 5 \\ x - 4 & \text{for } x \leq 5 \end{cases}$$ This means that the value of $$f(x)$$ depends on the value of $$x$$. Specifically: - For $$x > 5$$, the function follows the expression $$f(x) = \dfrac{5}{x}$$. - For $$x \leq 5$$, the function follows the expression $$f(x) = x - 4$$. If you have a specific question regarding this function (e.g., evaluating it at a particular value, finding limits, or analyzing continuity), feel free to ask! ### Do you want any further details or clarifications? Here are some related questions: 1. What is the value of $$f(6)$$? 2. Is this function continuous at $$x = 5$$? 3. What happens to $$f(x)$$ as $$x$$ approaches 5 from the right? 4. How would you graph this function? 5. What is the domain and range of this piecewise function? **Tip:** When working with piecewise functions, always check the behavior at the transition points (in this case, $$x = 5$$) to ensure continuity and correct interpretation.
