basically
\[x _{2}=x _{1}-\frac{ f \left( x _{z} \right) }{ f'(x_{1}) }\]

Answer 3

the z is suppose to be a one

Answer 4

correct - so where are you stuck?

Answer 5

I have to round to four decimal points and when I plug in negative one, the answer I get is wrong

Answer 6

the question says: "Find the next two in the series"

so you are supposed to find \(x_2\) and \(x_3\)

Answer 7

please show your work so I can help spot where you may have made a mistake

Answer 8

Never mind, I figured out what I did wrong, I had the answers for
\[x _{3}\]
and
\[x _{4}\]
