Is it possible for two different numbers, when
squared, to give the same result? what does this
result tell you about solving an equation when the
variable is squared? how many solutions will an
equation like this have? will there always be the
same number of solutions for any equation with a
squared variable? explain.

Yes. Squared variables usually have two solutions, unless they are 0 (1 solution) or negative (no solution).

Step-by-step explanation:

Solving the generic x² = c has two solutions when c>0, one solution when c=0, and no (real) solutions for c<0.

When c>0, the solutions are x = √c and x= -√c.

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.
