Question

evaluate f"(c) at the point. f(x) = 3-x/2x+3
C=-2

Answer 1

f(x)=(3-x)/(2x+3), u = 3-x , v= 2x+3 , u'=-1 , v'=2
f'(x) = u'v+uv' -2x-3+ 6-2x
------- = ------------ , u = -2x-3+ 6-2x , v = (2x+3)^2
v^2 (2x+3)^2
f''(x) = u'v+uv' , use the same way
-------
v^2

Answer 2

ok i was doing it the right way yah:) lol

Answer 3

ok g'luck

Answer 4

thanx

Answer 5

wait, a sec, this looks like a quotient rule problem, yet u state the product rule?

Answer 6

yeah i think i'm lost at the f''
