Now, set it equal to zero and find the roots. Those value(s) are your critical point(s).

critical point is ((-7,6),0)?
anonymous

it's marking me wrong.

why is it 0 when you clearly found the value to be \(\frac{7}{6}\)...
anonymous
  • anonymous
that's the problem.. after i find the critical point what do i do?

how would i write the point?
abb0t
  • abb0t
That is your only critical point.

just plug into original function?
anonymous
  • anonymous
yes but it has to be written as a point @abb0t
abb0t
  • abb0t
Yes, plug it into original.
