The position of an object moving along a line is given by the function . Find the average velocity of the object over the following intervals. (a) [1, ]
(b) [1, ]
(c) [1, ]
(d) [1, 1h] where h0 is any real number.

the answer is 8/21

hope this

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
