この問題の図示が難しくて出来ません 分数の三次関数のグラフの書き方を教えてください! お願いします!!

3次曲線と接線 99 とができるような, a, bの条件を求め, 点 (a, b) の存在する領域を図示せよ。 点(1,0)を通って, 曲線 y=x²+ax²+bxに異なる3本の接線をひくこ 精講 曲線 y=f(x)の接線の方程式は, 接点(t, f(t)) により決まります. このときの接線の方程式は y=f'(t)(x-t)+f(t) であり,これが点(α, b) を通ることから,t の方 程式 b=f'(t)(a-t)+f(t) ......(*) を得ることができます. この方程式をみたす tを 求めれば,その点における接線が1本ひけること になります。 すると, 3次関数のグラフでは接点 が異なれば接線も異なるので, 接線の本数=接点の個数 =方程式(*)の実数解の個数 ということになります。 解答> 解法のプロセス 接線の方程式 y=f'(t)(x−t)+ƒ(t) y=x³+ax²+bx y'=3x²+2ax+b 曲線上の点(t,t+at+bt) における接線の方程 式は f(t)=2t³—(3—a)t²—2at—b とおく. 3次関数のグラフでは接点が異なれば接線 も異なるので 点 (1, 0) を通る接線が3本ひける ⇔f(t)=0 が異なる3つの実数解をもつ ↓点(1,0)を通る 0=f'(t)(1-t)+f(t) ↓ (*) 方程式(*)が異なる3つの実数 解をもつ y=(3t²+2at+b)(x−t)+t³+at²+bt :: y=(3t²+2at+b)x-2t³-at² これが点 (10) を通るのは 0=-2t°+(3-a)t2+2a+bを通って接線をいく to your it のときである. 方 接線が3本存在する 225 yi f y=f(t)₁ KHUT
