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

     
    Use google for help with your math TBH

    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

    Note: "+_" is + or -

    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

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

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

    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

    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.

    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!
