問91 なぜこのように大量の場合分けが必要になるのか分かりません。 そりゃ計算したら答え変わるやーん って話ではあると思うんですけど…

26 4, 3 (3) は整 数であるから, ③ ④ を同時に 満たす整数が3 個になるのは 3(a-3)=a+3 のときである。 数学Ⅰ aa+la+2a+3x これを解いて a=6 これは 3 <a を満たす。 (i) α=3のとき ① は, 3x < 0 より x < 0 ② は, 0x0 となり, すべての実数x はこの式を満たす。 よって, ①, ② を満たす整数は無数にあ るから, 不適。 (m) 0<a<3のとき a> 0, a-3 <0であるから ①は x<3(α-3) xma a>0, 3(a-3) <0, 3(a-3)<a であるから, ①, ② を満たすxの範囲は x<3(a-3) よって, ①, ② を満たす整数は無数にあ るから、不適。 (iv) a = 0 のとき ① は, 0x<0 となるから, この式を満 たすxはない。 よって, ①, ② を満たす整数はないから, 不適。 (v) a <0 のとき a<0, a-3 < 0 であるから ①は x>3(a-3) xma ⑤ ⑥ を同時 に満たす整数 が3個になる のは I 3(a-3) 3(a-3)=a-3 ... ⑥ a-3 a-2 a-1 a 11 3(a-3) のときである。 これを解いて a =3 これはa < 0 ではないから, 不適。 (i)~(v) より a=6 * 92 (1) ||x-9|-1|2より -2≦x-9|-1≦2 ゆえに -1 |x-9 3 |x-9-1 は常に成り立つから x-913 を満たすxの範囲を求めればよい。 ①'より -3≤x-953 ゆえに 6 ≤ x ≤ 12 (2) ②を解くと, >0 より - k≤ x-45 le すなわち 4-k≦x≦4+k これと③が共通な範囲をもてばよい。 4 6 4+k 12 4+ k ≥ 6 って これを解いて k 2 2 (3) ④ が ③ を含めばよい。 (4) 4k 4-k したがって これを解いて 46 4+k212 k 28 x 124+kx
