Diketahui fungsi f:x→4x-1. Tentukan nilai fungsi f untuk x=-5,-3,-1,0,2,4, dan 10.

itu x nya tinggal diganti sama -5, -3,-1, 0,2,4, dan 10.
f(x) = 4x - 1
f(-5) = 4(-5) -1
= -20 - 1
= -21

f(-3) = 4(-3) - 1
= -12 - 1
= -13

f(-1) = 4(-1) - 1
= -4 - 1
= -5

f(0) = 4(0) - 1
= 0 - 1
= -1

f(2) = 4(2) - 1
= 8 - 1
= 7

f(4) = 4(4) - 1
= 16 - 1
=15

f(10) = 4(10) - 1
= 40 -1
= 39
