An ice cream shop's goal is to sell a mean of 45 ice cream cones per day. in one week, it sold the following numbers of ice cream cones each day.

54, 45, 33, 39, 48, 40, 41

how many more ice cream cones would it have had to sell during the week to meet its goal?

a. 15
b. 25
c. 35
d. 5

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.
