Question

Tolong bantu jawab ya, makasiii!

Answer 1

G(x) melalui titik (1, 3) dan (2, 7)
x1 = 1
y1 = 3
x2 = 2
y2 = 7

(y - y1) / (y2 - y1) = (x - x1) /(x2 - x1)
(y - 3) / (7- 3) = (x - 1) /(2-1)
(y - 3) /4 = (x - 1) / 1
y - 3 = 4(x - 1)
y - 3 = 4x - 4
y = 4x - 4 + 3
y = 4x - 1
g(x) = 4x - 1

g(-1) = 4(-1) - 1 = -4 - 1 = -5
g(1) = 4(1) - 1 = 4 - 1 = 3

g(-1) / g(1)
= -5/3
