Question

Tolong kerjakan, tolong bantu saya,

Answer 1

14) 3x + 6 = 12

x = (12-6)/3

x = 2

17)
g(-2) = -2a + b = -4
g(-6) = -6a + b = 12
~~~~~~~~~~~~~~~~ -
4a = -16
a = -4

-2(-4) + b = -4
b = -8 - 4
b = -12

g(x) = -4x - 12

20) n(P) = 4
n(Q) = 3

banyaknya korespondensi satu² = 0

karena n(P) ≠ n(Q)
