Question #3d2b8

Answer 1

The answer is `B`, which gives `8`

Explanation:

If we compute the derivatives on both sides of `x = 4`, we see that

`f'(x) = {(8, x < 4), (2x, x ≥ 4):}`

Now we see that when `x = 4`, both values are equal, or give `8`. Thus the function is differentiable and the answer is `b`, or `8`.

Hopefully this helps!
