Question

Ada yang bisa bantu 12,13,14?
bantuan mu sangat berharga!:))

Answer 1

12. f(-3) = ((-3)² - 3) / -3 = (9-3)/3 = 6/3 = 2 (C)

13. f : x -> 3 - 4x
f(a) = -9
3 - 4a = -9
-4a = -9 - 3
-4a = -12
a = -12/-4 = 3 (D)

14. m = (y1-y2) / (x1-x2) = (4-(-2)) / (-3 - (-8))  = 6/5 (D)

semoga membantu
