f(x)(a+2)=3x^2+2

解

f (x) (a + 2) = 3 x^{2} + 2

(h, k) = (0, \frac{2}{a + 2}), p = \frac{a + 2}{12}

解答ステップ

y (a + 2) = 3 x^{2} + 2

y (a + 2) = 3 x^{2} + 2

を標準的な形式で書き換える:

4 \cdot \frac{a + 2}{12} (y - \frac{2}{a + 2}) = (x - 0)^{2}

ゆえに放物線の特性は:

(h, k) = (0, \frac{2}{a + 2}), p = \frac{a + 2}{12}
