You mean microsoft word?

Uh huh.

You might have to do what I do, and upload the file to Imgur. I'm not super techy though, so I'll leave it to someone else to answer properly

Do you need a imgur account?

Also if anyone can help me with these Q's it would be great:

4. g(x)=2x-1.find x if
a. g(x+1)=3
b. [g(x)]^2=3

The second one could've been done by quadratic formula


Also, no.

Thanks

Also sorry for the overburdening of questions:

5. a. g(x)= x +(1/x)
Prove that g(x)g(x+(1+x))=g(x^2)+3
b. f(x)= (a^x+a^(-x))/2
Show that f(2x)=2[f(x)]^2-1
c.g(x)=log⁡((1+x)/(1-x)  .Show that g(2x/(1+x^2 ))=2g(x)
d. f(x)=log⁡((x+1)/x)
Show that:
I.   F(1)+f(2)+f(3)=log4
II.   F(1)+f(2)+…+f(n)=log(n+1)

Before tackling these questions, can I ask about if you've revised how functions actually work?

Given that Rui has now shown you very clearly how these kinds of questions work, I would recommend giving the new ones a go yourself. Try to work through them slowly, and if you really need more help then upload the work you've done. Then, we can help you figure out the next step, so you can keep working through them yourself. Giving you a billion answers won't help you learn, if you don't try to do some of the work yourself.

I did it last term for school but these were unanswered questions from a while ago which I found out today. The reason why it was unanswered was because I wasn't sure of how to do it back then

So have you tried looking over your resources and figuring how to do them now instead of blindly giving us your unfinished homework?

I did back then. Just curious but do these questions seem easy to you all?

Obviously to Rui and myself, who did Mathematics a while ago, have continued to do Maths at uni, and studied pretty damn hard for the HSC, year 11 questions will be pretty straight forward. That doesn't mean it should be, or would be, easy for you. Ideally, it should become easy over time.

That's because we have all studied it before.

I recommend you grab your textbook and read over things before you try any questions.

Feeding answers does not help.

Hi! So i was wondering what the difference between a solution and a root is.
For example, when the discriminant = 0, it says theres one solution but two real equal roots and i have a diagram and all but i dont really understand that.
