Find 2 (a) lim + (z,y) >(2, -3) 2+ 4ry -5y- (b) lim (z,y) > (1,1) I2 - y2 Note: If your answer is a fraction, type it into Moodle as a/b for the fraction: 4. Check Show that the lim (I,y) +(0,0) 4 + y2 does not exist by applying the two-path method: Choose two suitable paths and evaluate the limit for these paths: Path 1: y= Value of the limit for this path: Path 2: y= Value of the limit for this path: Note: If a fraction occurs in your answer, type it into Moodle as a/b for the fraction: 4
