Question

Diketahui f(x)=2x+4 jika domain f(x)=(-1,0,1,3,5) Rangenya Adalah?
(tolong jawabannya full ya)

Answer 1

F(x) = 2x+4
f(-1) = 2(-1)+4
        = -2+4
       = 2
f(0) = 2(0)+4
      = 0+4
      = 4
f(1) = 2(1)+4
      = 2+4
      = 6
f(3) = 2(3)+4
      = 6+4
      = 10
f(5) = 2(5)+4
      = 10+4
      = 14
Range adalah : 2,4,6,10, 14
