(2, 3) and (2, 2)
(-5, 2) and (-5, 1)
(6, 5) and (6, -5)
(-1, 0) and (-1, 6)
A function cannot reuse a value of x.
Each value of x can only appear once in a function.
Answer:<em> </em><em>a)</em>

b) x² + 8x - 84 = 0
Answer:
12*5/6*4 = 40 liters
Step-by-step explanation:
Answer: option D) An = 3an - 9a
Justification:
1) That is an arithmetic sequence which you prove by determining the difference between two consecutive terms (which shall be constant if it indeed is an arithmetic sequence):
2)
Second term - first term = -3a - (-6a) = -3a + 6a = 3a
Third term - second term = 0a - (-3a) = 3a
Fourth term - third term = 3a - 0a = 3a
Fith term - fourth term = 6a - 3a = 3a
Therefore, it is an arithmetic sequence with difference d = 3a.
3) the general rule for the nth term of an arithmetic sequence is given by the formula:
An = Ao + d (n - 1)
Where Ao = -6a and d, as determined above, is 3a
=> An = -6a + 3a (n - 1)
Expand the parenthesis (distributive property) =>
An = -6a + 3an - 3a = -9a + 3an = 3an - 9a = option D. <------- answer.
