Jawaban:

1. f(-3) = 36

f(-2) = 10

f(-1) = -2

f(0) = -6

f(1) = -2

f(2) = 10

2. h(2) = 19

3. m (gradien) = 2/5 atau 0,4

4. Tinggi Jendela = 8m

5.

Penjelasan dengan langkah-langkah:

1. f(x) = 4x² - 6

f(-3) = 4(-3²) - 6 = 4 × 9 - 6 = 36

f(-2) = 4(-2²) - 6 = 4 × 4 - 6 = 10

f(-1) = 4(-1²) - 6 = 4 × 1 - 6 = -2

f(0) = 4(0²) - 6 = 0 - 6 = -6

f(1) = 4(1²) - 6 = 4 × 1 - 6 = -2

f(2) = 4(2²) - 6 = 4 × 4 - 6 = 10

2. h(x) = 5x² - 1

h(2) = 5(2²) - 1

= 5 × 4 - 1 = 19

3. y2 - y1 = 4 - 2 = 2 atau 0,4

x2 - x1 6 - 1 5

4. a² + b² = c²

6² + b² = 10²

36 + b² = 100

b² = 100 - 36 = 64

b = (akar)64

b = 8

Tinggi Jendela = 8m
