tolpng jawab ya gan plizz

Kalo menurut aku ga bisa langsung dimasukkin 6 nya,klo langsung nanti jadinya bukan cari f(6) tapi jadi f(4)
f(x-2) = 3x-5
f(6-2) = 3(6)-5
f(4) = 18-5
f(4) = 13

jadi,kita cari nilai x dulu
x-2 = 6
x = 6+2
x = 8

f(x-2) = 3x-5
f(8-2) = 3(8)-5
f(6) = 24-5
f(6) = 19
semoga membantu,maaf kalo pendapatku salah:)

f(x - 2) = 3x - 5
f(x - 2 + 2) = 3(x + 2) - 5
f(x) = 3x + 6 - 5
f(x) = 3x + 1

f(6) = 3 × 6 + 1
f(6) = 18 + 1
f(6) = 19
