Math Problem Statement
Evaluate the piecewise function at f (-1) {x2-2 x <2 f(x) = 14+12-5| x > 2
Solution
Let's evaluate the given piecewise function at .
The function is defined as:
\begin{cases} x^2 - 2 & \text{if } x < 2 \\ 14 + |12 - 5| & \text{if } x > 2 \end{cases}$$ To evaluate $$f(-1)$$, we first determine which piece of the function applies. Since $$-1 < 2$$, we use the first case of the function: $$f(x) = x^2 - 2$$ Substituting $$x = -1$$: $$f(-1) = (-1)^2 - 2 = 1 - 2 = -1$$ Thus, $$f(-1) = -1$$.

What is the definition of a piecewise function? 3. Can you graph this piecewise function to show its behavior? 4. What is the domain of this piecewise function? 5. How would the function change if the condition for $$x = 2$$ was included? **Tip:** When evaluating piecewise functions, always check the condition first to determine which part of the function to use.Ask a new question for Free
