16. Ditentukan fungsi f(x) = -17 – 4x. Nilai f(-5) adalah … A.3B.-3C.5D.-5​

Jawaban:

A. 3

pengerjaan:

f(x) = (-17) – 4x

f(x) = (-17) – 4x

f(-5) = (-17) – 4 × (-5)

f(-5) = (-17) – (-20)

f(-5) = (-17) + 20

f(-5) = 3

semoga membantu

Materi : Fungsi dan Relasi

f(x) = – 4x – 17

f(-5) = – 4(-5) – 17

f(-5) = – ( -20 ) – 17

f(-5) = 20 – 17

f(-5) = 3 [ a. ]

Semoga bisa membantu
