Question

I really need help and nobody will help me. I think that I have this problem completely wrong but I don't know how to do it.

Answer 1

a) derivative with respect to x of the quotient of g of x divided by f of x when x = 3
When x=3 g(x) = 1
When x=4 f(x) = 2
d/dx[g(x)/f(x)] = d/dx [1/2]

b) d/dx [f(g(x)] when x=4
d/dx f(0) when x=4
d/dx 2(0) when x=4 = 0
c) d/dx [(x+f(x))^2] when x=2
d/dx[(2+f(x))^2] when x=2
d/dx [(2+0)^2] = d/dx(2)^2= d/dx 4= 0

Answer 2

That is my answer that I got but I don't know if I have it right?

Answer 3

the correct answer is c

Answer 4

No I am supposed to evaluate them and I just evaluated them above but I don't know if I did it right.
