Diketahui fungsi f(x) linear. jika fungsi f(3x+2) = 6x+10,nilai f(-5) adalah
Jawaban Terkonfirmasi
F(3x + 2) = 6x +10
3x + 2 = -5
3x = -5 – 2
3x = -7
x = -7/3
f(-5)
= 6(-7/3) + 10
= -14 + 10
= -4

Jawab :
f(3x + 2) = 6x + 10
f(-5) = _____??
→ Mencari nilai x
3x + 2 = -5
3x = -5 -2
3x = -7
x = -7/3
→ f(-5) = 6x + 10
= 6(-7/3) + 10
= -42/3 + 10
= -14 + 10
= -4
