Calculus, please show work so I can understand. Thanks!

Try Evaluate lim along the stated paths. Enter DNE if the limit does not exist. (x,y) - (0,0) *2 + 5xy + y2 a. Along the path ac = 0: b. Along the path y = : 10 C. Along the path y = - : 7cy d. After looking at different paths, would you say lim exists or does not (x, y) - (0,0) 2 + 5ay + y2 exist? O Limit exists. O Limit does not exist
