midpoint (9,-6),(-1,2)

الحلّ

midpoint

(9, - 6), (- 1, 2)

(4, - 2)

خطوات الحلّ

(\frac{x _{2} + x _{1}}{2}, \frac{y _{2} + y _{1}}{2})

(x_{1}, y_{1}), (x_{2}, y_{2})

نقطة الوسط بين

(x_{1}, y_{1}) = (9, - 6), (x_{2}, y_{2}) = (- 1, 2)

= (\frac{- 1 + 9}{2}, \frac{2 - 6}{2})

بسّط

= (4, - 2)

f (x) = 2 x^{3} - 2 x^{2} - 84 x

f (x) = x^{2} + 1

x + y = 0

(2, - 1), (- 7, - 7)

y = 3 sin (2 x)
