f(x) = 2x - 10 hasil dari a. f(2m+7) b. f(3y-1) c. f(-2) d. f(0)

Mapel : Matematika
Kelas : VIII SMP
Bab : Fungsi

Pembahasan :
f(x) = 2x - 10

f(2m + 7) = 2(2m + 7) - 10
f(2m + 7) = 4m + 4

f(3y - 1) = 2(3y - 1) - 10
f(3y - 1) = 6y - 12

f(-2) = 2(-2) - 10
f(-2) = -14

f(0) = 2(0) - 10
f(0) = -10
