Final answer:
The equation for the absolute value function reflected across the x-axis and shifted left by 2 units is y = -|x+2|.
Step-by-step explanation:
To find the equation of the transformed function described, we must apply two transformations to the parent function y= |x|. First, reflecting the function across the x-axis multiplies the function by -1, resulting in y= -|x|. Second, shifting the function to the left by 2 units involves replacing x with (x+2), leading to y= -|x+2|.
