Reprezentati grafic functiile

Answer 1

U=intersecta, Numa trebe sa îl faci invers. Eu nu am putut din vina tastaturii.
a) f:R->R, f(x)=x+1 .
GfUOx=A(x,0)->f(x)=0->x+1=0->x=-1->A(-1,0). GfUOy=B(0,y)->f(0)=y->0+1=y->y=1->B(0,1)
b) f:R->R, f(x)=-x+3
GfUOx=A(x,0)->f(x)=0->-x+3=0->-x=-3->x=3->A(3,0)
GfUOy=B(0,y)->f(0)=y->0+3=y->y=3->B(0,3)
c) f:R->R, f(x)=2x
GfUOx=A(x,0)->f(x)=0->2x=0->x=-2->A(-2,0)
GfUOy=B(0,y)->f(0)=y->2•0=y->y=0->B(0,0)
d)f:R->R, f(x)=-3x+5
GfUOx=A(x,0)->f(x)=-3x+5=0->-3x=-5->x=-5+3->x=-2->A(-2,0)
GfUOy=B(0,y)->f(0)=y->-3•0+5=y->y=5->B(0,5)
e)f:R->R, f(x)= 2x-4
GfUOx=A(x,0)->f(x)=2x-4=0->f(x)=2x=4->x=2->A(2,0)
GfUOy=B(0,y)=f(0)=y->2•0-4=y->y=-4->B(0,-4)
f) f:R->R, f(x)=-2x-4
GfUOX=A(x,0)->f(x)=-2x-4=0->-2x=4->x=-2->A(-2,0)
GfUOy=B(0,y)->f(0)=y->-2•0-4=y->y=-4->B(0,-4)
