Question

use the function f(x)= 3x^2 - 4x +1. find the derivative f(x)

Answer 1

ok Just find derivatives of each term

Answer 2

derivative of 3x^2= .....

Answer 3

d/dx(-4x)=....

Answer 4

d/dx(1)=......

Answer 5

Can you find them ?

Answer 6

how do you find d

Answer 7

d for ?

Answer 8

d/dx(1)

Answer 9

1 is a constant .Derivative of constant=0

Answer 10

What about other 2 terms ?Did you get them ?

Answer 11

well i got 6x as my answer after setting it up as 3(x+h)^2 -4x +1 -(3x^2-4x+1)

Answer 12

6x is right for first term ..But you missed 1 term

Answer 13

4(x+h)?

Answer 14

Well Are you required to find answer using this method only ?

Answer 15

Anyways its -4(x+h) instead of -4x

Answer 16

so the answer is 6x -4 instead of just 6x

Answer 17

yes :)

Answer 18
