## Decreasing Increasing or Constant - College Algebra

• 0:00 - 0:05
So, to summarize what we can say about function behavior, or at least this
• 0:05 - 0:10
aspect of it. If the value of the function goes down as the value of x goes up,
• 0:10 - 0:14
then we say that the function is decreasing. Just like over here where it's
• 0:14 - 0:18
sloping down. Now if instead f of x increases as x increases, then we say that
• 0:18 - 0:23
the function is increasing. Like in this part of the graph. The third option is
• 0:23 - 0:28
that f of x doesn't change at all as x increases. Here, f of x is a constant. So
• 0:28 - 0:32
here I've drawn another sort of silly looking graph, and I'm going to divide it
• 0:32 - 0:37
into several regions. So for each of the regions of the domain that I've split
• 0:37 - 0:41
up right here on the left, I'd like you to tell me if in that range in the
• 0:41 - 0:46
domain, the function, which is g of x in this case, is increasing, decreasing,
• 0:46 - 0:50
or a constant? Please pick one of these 3 values for each part of the domain.
