Question

Will fan if helped!

Evaluate the derivative of the given function at the given point

y=x^2 - x @ (3,6)

Answer 1

True

Answer 2

Easy, use the formula: (a+h)-F(a)
--------
h

Answer 3

And how would I incorporate it?

Answer 4

I really appreciate the help

Answer 5

plug in 6 in the a's

Answer 6

You are correct pickle

Answer 7

Have you been taught derivative yet? If yes, then find dy/dx and evaluate it at x = 3.

Answer 8

i mean plug it in the function.

Answer 9

so y = 3x - 1?

Answer 10

i mean
2x-1

Answer 11

y = x^2 - x
dy/dx = 2x - 1
dy/dx at x = 3 is: 2 * 3 - 1 = 6 - 1 = 5

Answer 12

(a+h)^2-(a+h)- a

Answer 13

is that it ranga? what about ((a+h) - f(a))/h ?

Answer 14

that equation confuses me

Answer 15

Ok, are you confused about what you post, or if you are correct?

Answer 16

just plug in (a+h) in the x's and then do (minus a) at the end of that equation because there's is - f(a) at the end of the formula

Answer 17

If you have not been taught derivatives yet, then you will have to do it the other way and evaluate the limit. But if you have been taught derivatives this is the easier way.

Answer 18

ahh I see, thanks

Answer 19

You are welcome.

Answer 20

tell me what you found

Answer 21

y= 3x -1

x = 3

y= 3(2) - 1

y = 5

Answer 22

Good job :)

Answer 23

ok, it seemed a lot mroe complicated then it was since the equations seemed kind of daunting.

Answer 24

but thanks

Answer 25

The secret is to follow the formulas
