Question

Suppose f (1) = 2, f ΄(1) = 3, g(1) = 5, and g΄(1) = -4. Evaluate (f g)΄v at x = 1.

can someone help me figure out how to solve the problem and walk through the steps????? Thanks so much :) im doing independant calculus and i really want to learn!!!

Answer 1

i think you are missing some operators .. is that function composition? and what is v?

Answer 2

if you can post a picture of the problem, that might help iron out some of the confusion

Answer 3

i dont really know...... there was never any of these types of problems in the lesson and then it just gave me this problems so im a little confused...... :P

Answer 4

post a picture using the [attach file] button so that we can see the problem. Otherwise your inexperience will simply muddy the issue.

Answer 5

this: (f g)΄v

makes no sense as is. if you copy and pasted it there are notations that simply do not copy over sometimes.

Answer 6

lol, dang

Answer 7

well, as is, the best I can determine is to use the product rule to determine the derivative of f, times g:

(fg)'= ____ + ____

Answer 8

but that "v" makes absolutely no sense

Answer 9

maybe, "v" was determined in a previous problem? it has nothing to do with the information in question9

Answer 10

i dont think so......... but thanks :P
