Graficul funcției de gradul I
este o dreaptă
pentru a trasa graficul sunt suficiente două puncte
construim mai întâi un tabel de valori
apoi sistemul de axe de coordonate pe care fixăm punctele aflate anterior
apoi prin cele două puncte trasăm dreapta care reprezintă graficul funcției
9
Graficul funcției de gradul I
fie funcția
f:R→R, f(x)=x+4x | 0 -4
y | 4 0
10
Multiple Select
Graficul funcției f(x)=x+1 este
11
A(x,y)∈Gf ⟺f(x)=y
A(2,4)∈Gf⟺f(2)=4
B(−2,2)∈Gf⟺f(−2)=2
12
Multiple Select
f:R→R, f(x)=x+3
Selectați punctele care aparțin graficului funcției.
A(0,3)
B(1,5)
C(3,6)
D(−3,0)
