Answer:
 1)  D. distributive property
 2)  C. D=all real numbers; R = {y | y ≥ 0}
Step-by-step explanation:
1) We observe that the factor of -4 has been multiplied by each of the terms of the binomial in parentheses. This is an application of the distributive property.

2) Any polynomial has a domain of all real numbers. The range of an even-degree polynomial will be limited by its extreme value. Here, the vertex of this quadratic function is (1, 0), so the range is all non-negative real numbers.
 F(x) = x^2 -2x +1 = (x -1)^2
Any square will have a minimum value of 0. For this function, that occurs at ...
 (x, y) = (1, 0)
The range will be values of y equal to or greater than zero.
