Final answer:
The absolute value of x² is differentiable at all real values of x.
Step-by-step explanation:
The absolute value of x² is differentiable at All real values of x.
The absolute value function, denoted as |x|, is defined as the distance between x and 0 on the number line. When we square x², the result is always positive or zero. Therefore, the absolute value of x² is also always positive or zero and is differentiable for all real values of x.
