c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

2nd one in the first row is correct

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

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.
