Penjelasan dengan langkah-langkah:

langkah:1.

cara melukis;

1.

g(x) = 3 - 2x

Dg = { | x-2 < x ≤ 3 , x ∈ R }

g(-2) = 3 - 2( -2 )

. = 7 ---------> ( -2 , 7 )

. = 3 + 4

g(3) = 3 - 2 (3 )

. = 3 - 6

. = -3 ---------> ( 3 , -3 )

2.

f(x) =2/3x + 4

Df = { x | x <- 3 , x∈ R )

pakai x = -3

f(-3) = 2/3 ( -3) + 4

. = = -2 + 4

. = 2 -----------> ( -3 , 2 )

titik potong dengan ;

sb. x ------------> f(x) = y = 0

2/3 x + 4 = 0

2/3 x = -4

x = -4 : 2/3

x = -4 x 3/2

x = -6 --------------> ( -6 , 0 )

titik potong dengan ;

sb. y -----------> x = 0

f(x) = y = 2/3 ( 0 ) + 4

. = 4 ---------------> ( 0 , 4 )
