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