Which statements about the graph of the function f(x) = –x2 – 4x + 2 are true? check all that apply. -the domain is {x|x ≤ –2}. -the range is {y|y ≤ 6}. -the function is increasing over the interval (–∞ , –2). -the function is decreasing over the interval (−4, ∞). -the function has a positive y-intercept.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
