Persamaan Fungsi

1. y=>x^2
x={-2,-1,2,3,4}
y={4,1,4,9,16}
Titik koordinat={(-2,4),(-1,1),(2,4),(3,9),(4,16)}
cara:
y=x^2
=(-2)^2=4
={-1)^2=1
=(2)^2=4
={3}^2=9
={4}^2=16

2. y=<-x^2
x={-2,2,3,4,5}
y={-4,-4,-9,-16,-25}
Titik koordinat={(-2,-4),(2,-4),(3,-9),(4,-16),(5,-25)}
cara:
y=<-x^2
=-(-2)^2=-(4)=-4
=-(2)^2=-(4)=-4
=-(3)^2=-(9)=-9
=-(4)^2=-(16)=-16
=-(5)^2=-(25)=-25

Demikian Semoga membantu dan bermanfaat!
