2. Considere os conjuntos: A = {0,1,2,3} e B = {-1,1,3,5,6,7}
a) Faça uma tabela, e em seguida, construa um diagrama de flechas em que os elementos de A se
associam com os elementos de B com F = {(x, y), com xe A e y eBly = 2x -1}.

b) Essa relação é uma função? Justifique sua resposta.

c) Se esta relação caracterizar uma função, determine o domínio, o contra domínio e a imagem

•Domínio
•Contra-Domínio
•Imagem

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
