Question

f(t)=3t^2+6t^(1/2) find f^u (4)

Answer 1

what does
\[f^{u}\] mean?(besides the obvious?)

Answer 2

that's what I am confused on

Answer 3

maybe it is suppose to be f^t ?

Answer 4

i can see why. i don't know this notation. it really says
\[f(t)=3t^2+6t^{\frac{1}{2}}\] find
\[f^u(4)\]

Answer 5

i am thinking maybe it is
\[f^{''}(4)\] could that be it?

Answer 6

of course i am just guessing.

Answer 7

oh yeah I see it now.

Answer 8
