Question

Determine the interval(s) on which the given function is decreasing?

Answer 1

Answer:

$(-\infty, -1) \cup (0, \infty)$

Step-by-step explanation:

The function is decreasing if, as x increases, the value of the function (y) gets smaller.  This means as you read the graph from left-to-right, the function is decreasing if the graph is falling.

From -infinity to -1, the graph is falling, then the graph rises (f is increasing) until x =0, then the graph falls again from x = 0 to infinity.
