Question

Reprezinta grafic functiile: a) f:R=R, f(x)=x-1; b) g:R=R, g(x)=x+1/2; c) h:R=R. h(x)=-2x; d) u:R=R. u(x)=2;

Answer 1

Pt a reprezenta grafic o functie trebuie sa calculezi

1)Intersectia Ox
f(x)=0⇒x-1=0⇒x=1⇒A(1,0)-coordonate
2)Intersectia Oy
Calculam f(0)-inlocuim x cu 0⇒f(0)=0-1=-1⇒B(0,-1)
Asa faci la toate celelalte unde nu stii intreaba-ma.
