Functions are used to represent graphs, and vice versa.
The function represented by the graph is
The graph (see attachment) is an absolute value graph.
An absolute value graph is represented as:
Where
The vertex is the minimum or the maximum point on the graph.
So, we have:
The function becomes
The function also passes through the point (-1,0).
So, we have:
Remove the absolute bracket
Subtract 3 from both sides
Divide both sides by 3
Substitute -1 for (a) in
Hence, the function represented by the graph is

Answer:
D. The distance from the mean to an inflection point
Step-by-step explanation:
We rarely encounter the actual formula for the normal PDF. It is ...
In fact, the inflection points are at x = ±1, where the curve changes from being concave downward to concave upward.
So, one standard deviation is the distance from the mean to an inflection point.
