Okay. >.>

Answer 6

@Vocaloid Can you check my answers?

Answer 7

and help me on the ones I'm not sure of?

Answer 8

am I checking your math or am I checking your coding?

Answer 9

Math

Answer 10

where are the original problems

Answer 11

There they are, in number order

Answer 12

I'm a little stressed out right now but I'm going to see if one of my friends can help you ;_;

2, 3, 4, 5, 7, 8, 11 are correct.

For 10 I assume you mean \[f(x)=\frac{ x-3 }{ 2(x-5) }\] and made a small typo there, but otherwise it's right

Answer 14

For number 1, (2.795,-2.583) and (-0939,-10.061)?

Those are the two minima yes, not too easy to find though! There should be a turning point that's a maxima as well between them, if you're looking for that point as well.

Also in question 6, there are 4 sign changes and hence the rule tells us that all roots are positive..

Answer 16

For number 6 are the roots,
\(\large1,\frac{1}{2},\frac{1}{4},5,\frac{5}{2},\frac{5}{4}\)?

Answer 17

I will be right back
