For the following function, first complete the table on your own and then, based on the table, find the given limits. Let f(x)=(x^(2)-x-12)/(x+3). (Enter DNE if a value does not exist. If applicable, enter -∞ or ∞ if a limit does not exist and approaches infinity, or DNE if a limit does not exist in another way.)
f(x) 3.1 -3.01 ? 3.001 ? -3 ? 2.999 ? 2.99 ? 2.9 ?
a. lim f(x) = 3
b. lim f() =
c. lim f =
