Which statement is true of the function f(x) = -x? check all that apply.
the function is always increasing.
the function has a domain of all real numbers.
the function has a range of {y-00 < < o }
the function is a reflection of y =
x.
the function passes through the point (3.-27).

Step-by-step explanation:

"The function is always increasing" is false.  The function is always decreasing.

"The function has a domain of all real numbers."  True.  The function is a polynomial and thus has a domain of all real numbers.

"The function has a range of {y-00 << o }."  False.  The range is (-∞, ∞ ).

"The function is a reflection of y =  x."  True

"The function passes through the point (3.-27)."  False

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
