Points of intersection: (1.225,-1.58) and (1.225,1.58)

Step-by-step explanation:

Given

Required

The region area

Plot the graphs of and

Make y the subject in both equations

Square both sides

Rewrite

Take square roots

So, we have:

Take square roots

So, we have:

The point of intersection is:

Square both sides

Collect like terms

Divide by 2

Take square roots

So, the point of intersection is at: (1.225,-1.58) and (1.225,1.58)
