di ketahui f(×) =|2×-40| nilai dari f(-3) + f(-1) adalah
![]()
Materi : Fungsi dan Relasi
f(x) = |2x-40|
Nilai f(-3)
f(-3) = |2(-3) - 40|
f(-3) = |- 6 - 40|
f(-3) = |-46|
f(-3) = 46
Nilai f(-1)
f(-1) = |2(-1) - 40|
f(-1) = |- 2 - 40|
f(-1) = |-42|
f(-1) = 42
Maka Nilai f(-3) + f(-1) = 46 + 42 = 88
Semoga bisa membantu
