The weight of the water exerts pressure on a diver. At a depth of 10 feet, the water pressure is 19.1 pounds
per square inch (psi) and at a depth of 14 feet, the
water pressure is 20.9 psi. Complete the statements,
then sketch the qualitative graph of this function.

The input, or x variable is __
The input, or y variable is __

look a the sides they are perpendicular

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.
