Given that a the four whole numbers a, a, b and c have
a mode of 7
a median of 8.5
a mean of 9
Work out the value of a, the value of b and the value of c.

a+b= 17 , ais mode=7 , b= 10 ,c =36_24=12

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.
