Math Problem Statement
Let f be the piecewise function given by f(x) = {8 - x^2 if x < 5, x + 8 if x ≥ 5}. Let g be an unknown function with domain (-∞, ∞). Which of the following is equal to the one-sided limit lim[x→5] g(f(x))? (Hint: Graph the function f)
Solution
Let's carefully analyze this problem step by step.
Given Information:
We have two functions:
- is a piecewise function defined as: [ f(x) = \begin{cases} 8 - x^2 & \text{if } x < 5, \ x + 8 & \text{if } x \geq 5. \end{
