Discussion Topic The graph of a quadratic relationship is in the shape of a parabola Parabolas are symmetric arcs and are useful for modeling relationships such as the height of a projectile over time or the curve of the cables on a suspension bridge Think about where you have seen a parabolic arc in real life. What unique features did it have, and where did you see symmetry in the relationship?​

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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.
