The idea of a rigid motions is a
significant concept in geometry.
Explain what a rigid motion is and why it
is important. Using the diagram below
identify the specific rigid motions used
for the following shapes.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
