Question

Qz.
f(x) = x² × x - x × 1
f(5) + f(3) =?​

Answer 1

Penjelasan dengan langkah-langkah:

• → Nilai f(5) = ?

f(x) = x² × x - x × 1

f(5) = 5² × 5 - 5 × 1

f(5) = ( 5.5 ) × 5 - 5 × 1

f(5) = 25 × 5 - 5

f(5) = 125 - 5

f(5) = 120

• → Nilai f(3) = ?

f(x) = x² × x - x × 1

f(3) = 3² × 3 - 3 × 1

f(3) = ( 3.3 ) × 3 - 3 × 1

f(3) = 9 × 3 - 3

f(3) = 27 - 3

f(3) = 24

• → Menentukan Gabungan Nilai

= f(5) + f(3)

= 120 + 24

= 144 ✔️
