1) Put n=2 in each of the offered expressions and see which one gives you 318 (the second house number).
  A) 292 + 13*2 = 318 . . . . a good candidate
  B) 292*2 = 584 (nope)
  C) 292*2 + 13 = 597 (nope)
  D) 13(2 + 292) = 3822 (nope)
The appropriate choice is ...
  A) 292 +13n

2)The squared term in the product is 2mx^2. The squared term in the given expression is -6x^2. Comparing the coefficients, we have
  2m = -6
  m = -3
The appropriate choice for the value of m is ...
  C) -3

3) The end point of one segment matches up with the beginning of the next except in the region 3 ≤ x < 4.
The appropriate choice is ...
  B) -8 ≤ x < 3 and 4 ≤ x < 8
