A h'(-1) = ?

B k'(1) = ?

Answer 1

ok this is what you do.
use the formula
\[(fg)=f'g+g'f\] then plug in the numbers you get for
\[f(1),f'(1), g(1), g'(1)\] and you will get your answer

Answer 2

sorry i meant
\[(fg)'=f'g+g'f\]

Answer 3

link is not working, so i cannot show further, but that is the idea

Answer 5

from the graph of f we see that
\[f(1)=0, f'(1)=\frac{2}{3}\]

Answer 6

you are on your own with g, because i cannot tell what
\[g(1)\] is

Answer 7
