Math Problem Statement

If f(x) = {3x+17x−4if −3<x<2if 3<x<6, then find the value of f(x) at x = -2. -18 -5 -8 10

Solution

The function f(x)f(x) is defined piecewise with two different expressions depending on the interval of xx. The function appears to have an issue with formatting, so let's clarify it based on standard piecewise notation. It seems like the function should be written as:

\begin{cases} 3x + 17 & \text{if } -3 < x < 2 \\ x - 4 & \text{if } 3 < x < 6 \end{cases}$$ To find the value of $$f(x)$$ at $$x = -2$$, we need to determine which interval this value of $$x$$ belongs to. ### Step 1: Identify the appropriate interval for $$x = -2$$ Since $$-2$$ falls within the interval $$-3 < x < 2$$, we use the first expression: $$f(x) = 3x + 17.$$ ### Step 2: Substitute $$x = -2$$ into the expression $$f(-2) = 3(-2) + 17.$$ Calculating this gives: $$f(-2) = -6 + 17 = 11.$$ It appears none of the provided answer choices match the correct calculation, suggesting there might be an error in the available options. Would you like to double-check the intervals or clarify anything further? Here are some related questions to deepen understanding: 1. How do you handle piecewise functions when $$x$$ is at the boundary of intervals? 2. What would be the value of $$f(x)$$ at $$x = 0$$? 3. How does the function behave between intervals? 4. What would be the value of $$f(x)$$ if $$x = 4$$? 5. Could boundary conditions alter the output of a piecewise function? **Tip:** Always confirm the function’s interval before substituting values, especially with piecewise-defined functions.
