 4- Verifique se a função é contínua no ponto (3,4) : f(x,y) = 2x +3y 
calcule também o limite quando (x,y) 
tende a (3,4)
5- f(x,y) ={
, verifique se é continua em (1,1)
 
6- Verifique se a função é continua em (0,0)
f(x,y) ={
,
7-Verifique se a função é contínua em (2,7)
f(x,y) ={
8)Verifique se a função é continua em ( 0,0)
f(x,y) ={
Em cada uma das funções seguintes , determine os pontos onde elas são contínuas 
	f(x,y) =x
f(x,y)= log ( x² + y²)
f(x,y) =
 f(x,y) = arc tg 
f(x,y)= tg 
	f(x,y)= arc sen 
f(x,y) = arc tg 
f(x,y) = arc cos
