Question

I could use some help with this question. I will post a picture of it :)

Answer 1

last one is -11

Answer 2

u blocked me @Teddylover101

Answer 3

yeah because you keep sending random numbers

Answer 4

those are answers.. for a b c &d...

Answer 5

@Teddylover101 .. i was sending answers...

Answer 6

no a,b,c & d are the choices. one of them is the answer. I'm sorry i didn't know

Answer 7

i need to find out how to solve that problem. & one of the answers is a b c or d. get it?

Answer 8

no u need to find F'(2) when F(x) is defined... as in a, b , c &d... these are 4 different questions.

Answer 9

@Teddylover101 ... i am sure those r not options..

Answer 10

hmm okay. if you say so. okay can you show me how you got ur answers please?

Answer 11

Answer 13

This is how you would do the first question, We are using the linear property of derivatives
for example

d/dx(F(x))= d/dx(2f(x)+g(x))
F'(x) =2*f'(x) + g'(x)
F'(2)=2*f'(2) + g'(2)

Answer 14

b) differentiating Fx we get
4f'x+5g'x
now put x =2 and all the values from the question

Answer 15

normal differentiation it is

Answer 16

c) differentiating Fx we get from product rule
fx.g'x +gx.f'x
and put again x = 2

Answer 17

final one is from quotient rule
(gx.f'x - fx.g'x) /(gx)^2

Answer 18

@Teddylover101
can u get the working of problems

Answer 19

wait how do i know what f'(x) is when we are given f'(2) ?

Answer 20

so u need to put x=2 n f(x) then it becomes f2... its just u need the value of everything at x=2

Answer 21

okay can you just show me how you did it so i can make sure i understand

Answer 22

ok so see..
