Find f(−5)

Solution

To find f(5)f(-5), we need to use the definition of the function f(x)f(x) at x=5x = -5.

From your piecewise function:

  • f(x)=(x+7)22f(x) = -(x + 7)^2 - 2 when x5x \neq -5
  • f(x)=1f(x) = 1 when x=5x = -5

Since you are looking for f(5)f(-5), we use the second part of the function definition where f(x)=1f(x) = 1 for x=5x = -5.

Thus, f(5)=1f(-5) = 1.

Here are 5 related questions:

  1. What is the value of f(x)f(x) when x=4x = -4?
  2. How does the function behave for values close to x=5x = -5?
  3. What would f(x)f(x) equal for x=0x = 0?
  4. How would you graph this piecewise function?
  5. Can we discuss the significance of piecewise functions?

Tip: When working with piecewise functions, always carefully check the conditions for each segment to avoid confusion.
