Calculus
a=0,a=0, the function is discontinuous because limx→af(x)≠f(a)\(\lim\)_{x\(\to\) a}f\(\left\)(x\(\right\))\(\ne\) f\(\left\)(a\(\right\)); a=15,a=15, the function is discontinuous because the limit does not exist
a=3,a=3, the function is discontinuous because the limit does not exist; a=10,a=10, the function is discontinuous because limx→af(x)≠f(a)\(\lim\)_{x\(\to\) a}f\(\left\)(x\(\right\))\(\ne\) f\(\left\)(a\(\right\))
