Which is the best estimate for the average rate of change for the quadratic function graph on the interval -8 the less than symbol is supposed to have a line under it but i didn’t have that symbol like shown in the picture a) -1 b)-2 c) 1 d) 2

Actually I just took the test on usatestprep and got it wrong

the answer is D) 2

answer: #1 ads up by 8 and i don't know #2

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
