diketahui fungsi F:x>4x-1. tentukan nilai fungsi f untuk X= -5,-3,-1,0,2,4 dan 10

Rumus fungsi f(x)=4x-1
f(-5) = 4(-5) -1 = -21
f(-3) = 4(-3) -1 = -13
f(-1) = 4(-1) -1 = -5
f(0) = 4(0) -1 = -1
f(2) = 4(2) -1 = 7
f(4) = 4(4) -1 = 15
f(10) = 4(10) -1 = 39

kalau di saya F:x>4x-1 di ubah menjadi Fx = 4x-1
jadi....
kalau Fx= -5
maka, 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
