use the graph of f to determine intervals where f is increasing and where f is decreasing. select the correct choice below and, if necessary, fill in the answer box to complete your choice. a. over the interval, , the function f, is decreasing. the function is never increasing. b. the function is neither increasing nor decreasing.
Answer
Answer:
A. Over the interval $(-\infty, \infty)$, the function $f$ is decreasing. The function is never increasing.
Explanation:
Step1: Observe the graph
As we move from left - to - right on the $x$-axis, the $y$-values of the function are always getting smaller.
Step2: Determine increasing and decreasing intervals
Since $y$ always decreases as $x$ increases, the function is decreasing over $(-\infty,\infty)$ and never increasing.
