<span>The range of Cos(x) is [-1,1]. Therefore the range of ln(Cos(x)) will be the image of [-1,1] using the natural log function. However, the domain of ln(x) is (0,infinity) and the log function is strictly increasing with vertical asymptote at "x=0". Therefore, the range of ln(Cos(x)) will be:
(- infinity, ln(1) ] = (-infinity, 0] !</span><span>so its true </span>
Ummmm i believe your answer is A. just divide next time :)
Answer:
Step-by-step explanation:
Quadrilateral ABCD is parallelogram, because opposite sides are congruent and adjacent sides are not perpendicular.
