12番の問題です。どこが間違っているのでしょうか。

微分の仕方 導関数の値 (接線の傾き) を求める
-
x=1のときの接線の傾きである f'(0) f' (1) をそれぞれ求めよ
= ax²
(112) y = f(x) = -3x-²
0 = 7x³ + 5x² + 12
(11-4) y = f(x) = (4x-7)(9x + 2)
)=(5-x)4
(11-6) y = f(x) = (8x-4)³
x) = 4x5 (2x² + 2x − 1)
(x+4)
_x) = √2-x
F(x)=x²-1
f(x) = 2√√x²+x+1
f(x) = 11x + 4(x + 1)−¹

)=0 f'(1) = 31
0) = -500 f'(1) = -256
D)=0 f'(1) = 84

(11-8) y = f(x) = \x
(11-10) y = f(x) = (x − 1)¹⁰

x+1
x²+x+1
(112) f'(0) = 0
(11-4) f'(0) = -55
(116) f'(0) = 384
(11-8) f'(0) = -144
(11-10) f'(0) = -10
f'(1) = 6
f'(1) = 17
f'(1) = 384
f'(1) =
f'(1) = 0

(1²) f'(x) = (x² + 1) = = = ( x ² + 1) = =
f(0) =
2√2²+1

合成関数なのでルートの中身のx^2+1の微分をかける必要があります
