Question

Daerah hasil dari fungsi f:=4x-5 jika daerah asalnya (-2,-1,0,1,2,3,4) adalah

Answer 1

F:x =4x-5
f:-2 = 4(-2) - 5 = -8 -5 = -13
f:-1 = 4(-1) -5 = -4 -5 = -9
f:0 = 4.0 -5 = -5
f: 1 = 4.1 - 5 = 4-5 = -1
f:2 = 4.2 - 5 = 8-5 = 3
f: 3=4.3 - 5 = 12 -5 = 7
f:4 = 4.4. -5 = 16-5 = 11
daerah hasil ={-13,-9,-5,-1,3,7,11}
