Diketahui :
↪f(x) = - 2x + 5 atau
↪f(x) = -2 + 5x ➡ Soal Belum Jelas


Ditanta :
↪Nilai f(-4)

Jawaban :
=========


➡jika f(x) = -2x + 5

Maka, f(-4) :

= -2(-4) + 5
= 8 + 5
= 13✔


➡jika f(x) = -2 + 5x

Maka, f(-4)

= -2 + 5(-4)

= -2 - 20

= -22✔

f(x) = -2x + 5

f(-4) = -2(-4) + 5
f(-4) = 8 + 5
f(-4) = 13

(atau)

f(x) = -2 + 5x

f(-4) = -2 + 5(-4)
f(-4) = -2 - 20
f(-4) = -22
