The open circle at $\frac{7}{2}$ indicates that x cannot equal this value.

All values of x between - $\frac{3}{2}$ and $\frac{7}{2}$ are valid, thus

- $\frac{3}{2}$ ≤ x < $\frac{7}{2}$ → B

Look at the picture.

|AB| = r - |OA|

Use Pythagorean theorem:

$|OA|^2+10^2=14.5^2\\\\|OA|^2+100=210.25\ \ \ |-100\\\\|OA|^2=110.25\to|OA|=\sqrt{110.25}\to|OA|=10.5$

$Answer:\ |AB|=14.5-10.5=4$
