Question

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

Answer 1

The parent absolute value function f(x) = |x| is not decreasing over any interval. It is a V-shaped graph with its vertex at the origin, and it increases on the interval (-∞, 0) and increases on the interval (0, ∞). Therefore, it is not possible for it to be decreasing over any interval.
