Question

I need serious help on this packet, because I kind of get it, but at the same time I don't really understand it. I answered some of the questions which need to be checked for correctness and the ones that I don't have answers for, I need help on those. *If you need to explain each problem, so I have a better idea of what they are talking about on the packet.*

*My Answers are in a PDF File*

Answer 1

I think you got the answer, right? on the previous one

Answer 2

@satellite73 please, explain,

Answer 3

@satellite73 for which number

Answer 4

Agree, that's what he needs

Answer 5

ignore me

Answer 6

first page is all correct, ignore my previous comment

Answer 7

for 5) I think on (-1,0) f(x)<x

Answer 8

second page, i assume the \(f\) is the \(f\) on the first page right?

Answer 9

on [0,2], f(x) =x, hence it does not satisfy f(x) >x, take it off

Answer 10

on [3,4], f(x) <x

Answer 11

on (4,5] f(x) =x, get rid off
on (5,6) f(x) < x, get rid off the interval
hence, just [-6,-3) and [-2,-1) are the intervals in which f(x) >x

Answer 12

for 7) only -6 is the point when f(x) gets global minimum

Answer 13

f(-2) = 0, it's not minimum

Answer 14

f(0) is not the global minimum because (0, -2) is not on the graph.

Answer 15

is the first page correct or not

Answer 16

10b) f(-6) is minimum, hence at this point g(x) = f(-x) = f(6) = 5, hence it is maximum value of g

Answer 17

I checked one by one from 1 upto 10 now, why do you ask for the first page or the second page?

Answer 18

to do 11, you need do 10c, show me the graph

Answer 19

12 is the same, need graph

Answer 20

What's wrong with #5?

Answer 21

ok, 5) asks you find where f(x) > x, right?
at x =-1, f(x) =-1, hence f(x) \(\color{red}{=}\)x, not > x, ok?

Answer 22

a little bit up for x, for example, if x = -0.5, f(-0.5 ) = -1.5, hence f(x) \(\color{red}{<}\) x, it is not f(x) > x
got what I mean?
