This is in the wrong section X_X It should be in Off Topic Discussion.

Use google for help with your math TBH

[Typhoid]

Haha this belongs in the off-topic discussion bud.

[Arachnophobik]

O.O what are those alien-like languages on your test paper!

[Arpluvial]

I have moved this thread to the Off-Topic Discussio portion of the forums. :)

1. shut textbook

6. sleep
7. repeat


^^^^

thats how you pass classes


in all serioussness though just ask your teacher if he/she isnt cranky or google

Just a tip, all graphs with x^2 will be a parapola which is in simple words a happy or a sad face, happy if the x value is positive, sad when its a negative

Use the formula y=mx + c

Where y= f(x)
m= gradient
x= ur x value
c= y-intercept i.e point of line that is touching the y-axis

Hope this helps!

For the graph just substitute values of x as -1,-2,-3,0,1,2,3. Get values of y. Plot the graph. Its a parabola.

General equation of parabola in above problems in (x+_h)^2=+_4a(y+_k)

Convert the problem equation to gen equation.
Vertex is (h,k)
Intercepts i forgot :p

Note: "+_" is + or -

[yasshh]

For 2nd ss

Prove that both functions are one-one and onto i.e a bijection
If u see f inverse= g(x). Thats it i guess

Thx for brushing my brain

[Trenton]

Are you expecting someone to do every single one of them for you?

[obee]

It's suicide letting people doing your homework. You don't learn anything

[Xxnavysealxx]

Before I even tell u how to do it I need u to answer the following question


Does your teacher make you give her/him the paper you did the hw on?
ORRR
does he/she walk around and glance at your work then walk by? If yes then just right down random letters and numbers and set to go but if no then just do up to #13 f(x) is pretty much y so f(x)=5+6 squared is y=5+6 squared

[Itoopeo]

Those are easy but im too lazy to waste my time on painful f(x) functions ew!

Yo, get a CAS TI N-spire and make your classmates jelly that you can do all dem maths.

[Amadorbibidor]

Use yahoo ask for this stuff. This is AL Forum not Detention Global Association Forum duh.

[BlackAimZ]

My teacher actually requires us to use it in class O.o

Same, but we're banned from using the 'solve' command because several of my classmates are nuisances when it comes to learning how to do algebra.

As an educator, this thread makes me realize why our world is heading in the direction it is.

1. Stop
2. Fold ur hw to a paper airplane.
3. Crush it with ur very hands with all ur might.
4. Crumple it all up into a ball
5. Take the hw outside.
6. Throw it to the ground.
7. Grab as many flammable liquids/chemicals as you want.
8. Pour em all onto it.
9. Grab an axe colougne bottle (must have some inside).
10. Grab a lighter.
11. Put some protective gloves on.
12. Crank the wheel of the lighter.
13. Hold up ur axe bottle so that it is aiming towards the flame of the lighter.
14. Aim to the hw.
15. Push down the button on the axe.
16. The ball of hw will burst into flames, gradually burning.
17. Walk back and stay back, for safety.
18. Wait for the fire to burn down.
19. Take the fragments of the hw, and bury it.
20. Go back to school and tell ur teacher that ur dog ate ur hw.
Thats it! I use this method often and it works like a charm. Hope it helped! :D
