Step-by-step explanation:
The missing table is shown in the attachment.
Since the quadratic function has vertex at (0,3), its equation is of the form;
To find the value of 'a' we substitute any other point from the table say (1,2) to get:
Hence the function is
Now
The average rate of change from x=9 to x=10 is
53) Vertical angles are congruent, so
54) and
are supplementary, so
55) Because vertical angles are congruent, . Now, because DR bisects
, this means
56) This is a geometric sequence where the next term is obtained by multiplying the previous term by -2, so the next two numbers are 16, -32
