Larry and Tom were standing next to each other in the backyard when Tom challenged Larry to guess how tall he is. Larry knew his own height is 6.5 feet, and when they measured their shadows, Larry’s shadow was 8 feet long and Tom’s was 7.75 feet long. What is Tom’s height? Round to the nearest tenth

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.
