All of the following statements describe the relation shown except

the diagram represents a function.
the inputs are {-1, 0, 3, 4}.
the outputs are {-2, -1, 1}.
this relation could also be represented as {(-1, 1), (0, -2), (3, 1), (4, -1)}.

if the ordered pairs are supposed to match the diagram then they are wrong the set of ordered pairs should read:

{(-1, -1), (0, -2), (3, 1), (4, -1)}

nope.   happens to me as well.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
