To translate the graph of the function \( y = |x| \) horizontally, you need to modify the argument of the absolute value function.
To translate the graph 10.5 units to the left, you can replace \( x \) with \( x + 10.5 \).
Thus, the equation for the translated graph is:
\[ y = |x + 10.5| \]
This equation represents the original graph shifted 10.5 units to the left.
