Question

Help with a Newton's Method Problem.

Answer 1

sure

Answer 2

Hi, I know the formula but I just don't know how to incorporate :/

Answer 3

you are going to have to do a bit of guessing here, but you only need one iteration so it should be ok

Answer 4

first from the graph find
\[f(-\frac{1}{2})\]

Answer 5

Guess by sight?

Answer 6

what else can you do? you do not know the function. actually you don't even have to do that

Answer 7

if you have this drawn on a big piece of paper, but a ruler down tangent to the curve at (-1/2,-2) which is my guess. once the ruler is tangent to the curve there, see where it crosses the x - axis. that is your first iteration

Answer 8

The tangent line for f(-1/2) seems to fall around 0.6.
I guess that would be it :)

Answer 9

Yup, I'll go with A.
Thanks.

Answer 10

that would be my guess as well

Answer 11

but really it is just a guess.
