Elena goes for a long walk. This graph shows her time and distance traveled throughout the walk. What was her fastest speed, in miles per hour? *And I don't think it is A by the way??? Can you help? A.) 3 mph

B.) 2 mph

C.) 4 mph

E.) She is not moving

uhhh idk u yolo?

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.
