David goes into a candy store with $5.00.

he buys 9 peppermints for $0.15 each, and some giant lemon-heads.

each lemon-head candy costs $0.25.

what is the most number of lemon-heads david can buy?

a - base

b - exponent

so,

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.

7 is the median   7.875 is the mean
