    1. Determine whether the equation defines a function with independent variable x. If it does, find the domain. If it does not, find a value of x to which there corresponds more than one value of y.
    x|y| = x + 9

    2. Use the graph of the function to estimate: (See attached)
    a. f(2)
    b. f(-4)
    c. All x such that f(x) = 0

    (There are a half dozen more algebra problems in the attachment.)
