Describe the x-values at which the function is differentiable. (enter your answer using interval notation.) y = |x2 - 25|

Differentiable on the intervals (-∞, - 5) ∪ (-5, 5) ∪ (5, ∞)

Step-by-step explanation:

The graph will look like a W shape whose vertices are at x = - 5 and x = 5. The function is not differentiable at these values.
