# right top half semicircle from theorem Pythagoras using y=sqrt(1-x²)

# shift graph right using "x-1"

# create another left top half semicircle at the negative x-axis

#   using y(x) and y(-x) or y(|x|)

y1 = np.sqrt(1 - (abs(x1)-1)**2)

# left bottom half sqrt curve line using y=(x)**0.5

# vertical reflection for the graph using y = -1*(x)**0.5

# shift graph left using "x+2"

# create another right bottom half sqrt curve line using

#   vertical reflection y = -1*((-x) + 2)**0.5

y2_right = -1*((-x2_right) + 2)**0.5
