Question

use the graph of the rational function to complete the following statement. as x → 4⁻, f(x) → ___. as x → 4⁻, f(x) → □.

Explanation:

Step1: Analyze the left - hand limit

The notation $x\to4^{-}$ means $x$ approaches 4 from the left - hand side.

Step2: Observe the graph

Looking at the graph of the rational function, as $x$ approaches 4 from the left, the $y$ - values of the function $f(x)$ increase without bound.

Answer:

$\infty$
