f lim f(x) = L1 as x approaches a from the left and lim f(x) = L2 as x approaches a from the right. lim f(x) as x approaches a exists only if L1 = L2. true or false
"L_1=\\lim _{x \\rightarrow a^-} f(x)"
"L_2=\\lim _{x \\rightarrow a^+} f(x)"
Limit exist only if "L_1=L_2"
Hence, the given statement is true.
