What is the equation of the above function?
What is the equation of the above function?
The formula of an absolute value function is 
where m is the slope, a is the horizontal shift and b is the vertical shift. The slope can be found with any two adjacent integer points, e.g. 
and 
, and plugging them into the slope formula, 
, yielding 
. The vertical and horizontal shifts are determined by where the crux of the absolute value function is. In this case, at 
, and those are your a and b, respectively.
The formula of an absolute value function is

Which of the following absolute value functions is represented by the following graph?
Which of the following absolute value functions is represented by the following graph?
The equation can be determined from the graph by following the rules of transformations; the base equation is:
The graph of this base equation is:
When we compare our graph to the base equation graph, we see that it has been shifted right 3 units, up 1 unit, and our graph has been stretched vertically by a factor of 2. Following the rules of transformations, the equation for our graph is written as:

Let 
The graph of this basic absolute value function is a "V"-shaped graph with a vertex at the origin, or the point with coordinates 
. In terms of

The graph of this function can be formed by shifting the graph of 
left 6 units (
) and down 7 units (
). The vertex is therefore located at
