Answer:
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.
First you divide 12 by 3 to get 4, and then you multiply 210 by 4 to get 840, which is answer C. This is because if it is 210 patients per 3 weeks, 3 goes into 12 weeks 4 times, so you need to multiply. I hope this helps!

The domain is x ≥ 1 as x cannot be less than 1 or else it'll become negative in square root which you cannot find a value.
