Question

Di ketahui fungsi f:x → 4x-1,tentukan nilai fungsi f untuk x = -5, -3, -1, 0, 2, 4, Dan 10.

Answer 1

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

Answer 2

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
