Answer 2

huh well there are several ways.... posting an example would help people out here

Answer 3

It is a simple question with complex answers, you need to have ideas of limit at start, one can not tell you answering here

Answer 4

Exactly I agree with mainakang

Answer 5

f(x)=x+(9/x)

Answer 6

how would i find the derivative, step by step pleasssee

Answer 7

By product rule d/dx fg = f'g + fg', we let:

f = x + 7
f' = 1
g = e^(3x)
g' = 3e^(3x)

Then,

f'(x) = 3e^(3x)(x + 7) + e^(3x)
==> e^(3x)(3(x + 7) + 1)
==> e^(3x)(3x + 21 + 1)
==> e^(3x)(3x + 22)
