Question 323405
{{{graph(300,300,-10,10,-5,5,3*sin(1/(x+0.001)))}}}
{{{graph(300,300,-2,2,-5,5,3*sin(1/(x+0.001)))}}}
a) Yes, it provides a unique y value for each x input, although it is not continuous at {{{x=0}}}.
b) ({{{-infinity}}},{{{0}}}) U ({{{0}}},{{{infinity}}})
c) [{{{-3}}},{{{3}}}]
d) f(0) is undefined since 1/0 is undefined.
e) ymax=3
f) ymin=-3
