Jack observed that he got rashes whenever he ate white berries he picked from his backyard. he concluded that eating white berries causes rashes. which of the following statements will prove that there is a correlation and not causation between eating white berries and getting rashes? the rashes are cured when jack takes medicine. jack gets rashes only when he eats white berries picked from his backyard. the white berries cause digestion problems which are manifested in the form of rashes. the berry plant secretes a sap which causes rashes when it comes in contact with human skin.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

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.
