Question

Tolong bantu saya, besok dikumpulkan​

Answer 1

y== 2x² - 3x + 5

ordinat (y) = 4

2x² - 3x + 5 = 4

2x² - 3x + 5 - 4 = 0

2x² - 3x + 1 = 0

(2x - 1)(x - 1) = 0

x = 1/2 dan x = 1

Ambil salah satu, kita ambil x = 1

y = 2x² - 3x + 5

y' = 4x - 3

   = 4(1) - 3

   = 4 - 3

   = 1

m = y' = 1

Persamaan garis

(y - y1) = m(x - x1)

(y - 4) = 1(x - 1)

y - 4 = x - 1

y = x - 1 + 4

y = x + 3

Semoga membantu
