The domain of any function is the set of the values of x that will make the function correct. If we try to extend indefinitely the parabola with specified attributes above on the plane where it is drawn, the parabola will expand. This allows all the real numbers be the x-values. Thus, the answer is letter "C. All real numbers"
If you write a number over another number, it's called a FRACTION
The answer is 1/6
hope this helped :)
-2(3)(5+3-8-3(3))
=-6(5+3-8-9)
=-30-18+48+54
