1.9.8 Increasing and decreasing functions

Card 1 of 20

Tracing a graph from left to right, an upward-sloping graph represents an [     ] function.

A

Within a continuous interval, f′(x)f'(x)f′(x) cannot change sign without becoming zero or undefined.

B

For x1<x2x_1<x_2x1​<x2​, strict increase requires f(x1)<f(x2)\boxed{f(x_1)<f(x_2)}f(x1​)<f(x2​)​.

C

Tracing a graph from left to right, an upward-sloping graph represents an increasing function.

D

For a differentiable function, f′(x)<0\boxed{f'(x)<0}f′(x)<0​ means that fff is decreasing.
