Domain is set of all x-values. You are supposed to focus on the x-axis instead.
From the graph, the point starts from x = -5 and ends on x = 5. That means no values would exist after x = 5 or before x = -5.
Hence, the domain starts from -5 to 5.

Answer: B= A/(C+D)
Step-by-step explanation:
A = B(C+D)
Divide each side by B
A/B= C+D
Reciprocate both sides
B/A = 1/(C+D)
Now multiply each side by A
B = A/(C+D)
