Question

Given the function f(x) = x^2 + 13.5x + 45, use Newton's Method to find x⌄6 when x⌄0 = -7.

Answer 1

the 6 and 0 are supposed to be below the x

Answer 2

I know...

Answer 3

You show her/him and I will watch. XD

Answer 4

Do you even know how to use the formula?

Answer 5

Answer 6

Sort of maybe kind of. It has been awhile... That is why I wanted you to do it. xD

Answer 7

@zepdrix

Answer 8

Nope.

Answer 9

Answer 10

Ok, first off find the derivative of the function, since we will need it later.

Answer 11

You there?

Answer 12

Guess not, good luck homie

Answer 13

She isn't here... She is gone...

Answer 14

To check your answers here are all
\[
x_i \text{ for } i=0,1,2,3,4,5,6}
\]
{-7, -8., -7.6, -7.50588, -7.50002, -7.5, -7.5}

Answer 15

You can check that\[
x^2+13.5 x+45=(x+6) (x+7.5)
\]
so we got the actual root

Answer 16

Would be clearer for everyone if you'd please use the correct notation:

Given the function f(x) = x^2 + 13.5x + 45, use Newton's Method to find x⌄6 when x⌄0 = -7. Confusing

Given the function f(x) = x^2 + 13.5x + 45, use Newton's Method to find \[x _{6}\]

Answer 17

when the initial, "guessed," starting value is \[x _{0}=-7\]

Answer 18

do you know the formula for Newton's method? If so would you mind typing it out so that we can verify that you're working with the right formula?
