    Need help with 4 questions

    I had trouble with these four questions any help would be great!

    1. Identify the center and radius of the circles represented by the following questions

    (a) 3x - √3x+3y-y+ 1/12=0 (b) 12x + 12y+42y=0


    2. Let f(x)= 1/√x-2 and g(x)=√x+1.
    (a) Find the domain of each function.
    (b) Find the domain of (g/f)(x)

    3. Determine whether the functions are even, odd, or neither.

    (a) f(x)= x/√x+1 (b) g(x)=x - √x-7


    4. Let f(x)= x^5/120- x/6 + x.

    (a) Find the local minima and maxima.
    (b) Determine where the function is increasing and decreasing.

    *Sorry I didn't know how to put them in correctly but the / is divided by and the ^5 is to the fifth power and the √ is the square root

    Any help is greatly appreciated
