1. Jawaban BSunShine
Materi : Fungsi
f(x) = -3x - 2
f(-3) = -3(-3) - 2
f(-3) = 9 - 2
f(-3) = 7
f(5) = -3(5) - 2
f(5) = -15 - 2
f(5) = -17
f(-3) + f(5)
= 7 + (-17)
= 7 - 17
= -10 -
2. Jawaban gracenoverriel
F(x) = -3x - 2
Masuk pertanyaan :
F(-3) + F(5) ?
F(-3) = -3 (-3) -2
F(-3) = 9 - 2
F(-3) = 7
F(5) = -3 (5) -2
F(5) = -15 -2
F(5) = -17
F(-3) + F(5) = ?
7 + -17
-10.
