Q.

Jawaban:

[[ No 1 ]]

f(x) = 4x² + 4⁰ + 9⁰ + 2

f(2) = 4(2)² + 4⁰ + 9⁰ + 2

f(2) = 4(2×2) + 1 + 1 + 2

f(2) = (4×4) + 1 + 1 + 2

f(2) = 16 + 1 + 1 + 2

f(2) = 17 + 1 + 2

f(2) = 18 + 2

f(2) = 20✓

Nomor 1

f(x) = 4x² + 4⁰ + 9⁰ + 2

f(2) = 4(2²) + 1 + 1 + 2

= 4(4) + 4

= 16 + 4

= 20

Nomor 2

130 + 20

= 150

Nomor 3

5!

= 5 × 4 × 3 × 2 × 1

= 20 × 6 × 1

= 120

Nomor 4

2! + 2

= (2 × 1) + 2

= 2 + 2

= 4
