Question

find the derivative of f(x)=4x^3-1/x^2-3(3)sqrt(x)

Answer 1

do you need to use , [f(x+h) - F(x) ]\h or power rule

Answer 2

the power rule

Answer 3

fx^3-3fx-4x^5+12x^3+1=0...idk if it's right

Answer 4

i'll check

Answer 5

f(x)=4x^3-1/x^2-3(3)sqrt(x)
re writing question
y=4x^3-1/x^2-3.x^1/3
y=4x^3-x^-2-3.x^1/3
using power rule,
y'=12x^2-(-2)x^-1-3.1/3.x^-2/3
y'=12x^2+2/x-1/x^2/3
