Create a formula for a function
f
(
k
)
\displaystyle {f{{\left({k}\right)}}}
f
(
k
)
that has
f
(
2
)
=
8
\displaystyle {f{{\left({2}\right)}}}={8}
f
(
2
)
=
8
. Do not give a simple constant function (like
f
(
k
)
=
8
\displaystyle {f{{\left({k}\right)}}}={8}
f
(
k
)
=
8
) as your answer.
f
(
k
)
=
\displaystyle {f{{\left({k}\right)}}}=
f
(
k
)
=
