What is the domain and range of the relation represented by the set of ordered pairs? {(2, 6), (2, 0), (-4, -2), (-4, 6)}

A:
The mapping does not represent a relation.

B:
D: {0, 2, 6}
R: {-4, -2}

C:
D: {-2, 2, 6}
R: {-4, 0, 2}

D:
D: {-4, 2}
R: {-2, 2, 6}

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

step-by-step explanation:

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.

answer: (x+2) (x+3) are the binomials for your question : )

54.667> 54.666

17.889< 17.899

these are both true
