    Answer:

      8.   D. Constant

      6.   A. No

      16.   A. No solution

    Step-by-step explanation:

    8. There is no “x” on the right side of the equal sign in the function definition. There is only the constant 13/6. The function shown is constant.

    __

    6. The equation will graph as a parabola that opens to the right. Solving for y, you get …

      y = ±√(x+3)

    This is double-valued. A relation that gives two values for the same value of x is not a function.

    __

    16. In standard form, the two equations are …

    • x -7y = 28
    • x -7y = 1

    These equations are “inconsistent”. There are no values of x and y that can make them both be true. Thus, there is no solution.
