Nilai f ( -1 per 2 ) =??
tolong yang tau dijawab dong+caranya yah

Diketahui fungsi f (x) = 3x²-2x-5.

Jawaban Terkonfirmasi

F(-1/2) = 3(-1/2)² – 2(-1/2) – 5
         = 3/4 + 1 – 5
         = 3/4 – 4
         = 3/4 – 16/4
         = -13/4

F (x) = 3x²-2x-5
f (-1/2) = 3 (-1/2)^2 – 2 (-1/2) – 5
= 3 (1/4) + 1 – 5
= 3/4 – 4
= -3 1/4
