Question

Over which interval is the graph of the parent absolute value function f(x) = |x| decreasing?

(-00,00)
(-00, 0)
O (6,0)
O (0,00)

Answer 1

(-∞,0)

Explanation:

The graph of ƒ(x) = |x| is below.

The function is decreasing on (-∞,0) .

A is wrong. The function both decreases and increases on (-∞,∞).

C is wrong. The function is decreasing on (-6,0), but that is only a portion of the interval.

D is wrong. the function is increasing on (o,∞).
