The parent function of the function shown in the graph is the absolute value function, in this case, we visually we can notice that we have a vertical shift down by 2 units and vertical compression by 2 units.
For the vertical shift, we need to subtract 2 from the function.
For the vertical compression we need to multiply 2 to the x.
Therefore the equation that represents the graph is
ANSWER
B. y=|2x|-2
