Penjelasan dengan langkah-langkah :

2. 3, 6, 12, 24 ( geometri)

r = 6/3 = 2

U⁸ = ar(n-¹) = 3.2⁸-¹ = 3.2⁷ = 3.128 = 384

3. Persamaan garis melalui

titik (-2,0) // y = 3x + 2

dik :

y = 3x + 2, m = 3

Persamaan garis :

y – y¹ = m (x – x¹)

y – 0 = 3 (x + 2)

y = 3x + 6

4. Tentukan gradien :

m = ( y² – y¹) / (x² – x¹)

= 1 + 4 / -7 – 3

= 5/-10 = -1/2

5. f(x) = 4x + 4

daerah asal {-2,-1,0,1,2}

daerah hasil : {-4,0,4,8,12}

f(x) = 4x + 4

f(-2) = 4.-2 + 4 = -8 + 4 = -4

f(-1) = 4.-1 + 4 = -4 + 4 = 0

f(0) = 4.0 + 4 = 4

f(1) = 4.1 + 4 = 4 + 4 = 8

f(2) = 4.2 + 4 = 8 + 4 = 12

Pasangan berurutan:

{(-2,-4),(-1,0),(0,4),(1,8),(2,12)}
