Question

fie f{-3,-2,1,0,1}-R,f(x)=3×-1

Answer 1

F(-3)= 3×(-3)-1= -9-1=-10
F(-2)= 3×(-2)-1= -6-1=-7
F(-1)= 3×(-1)-1= -3-1=-4
F(0)= 3×0-1=-1
F(1)= 3×1-1=4
Nu stiu sigur daca e corect

Answer 2

f(-3)= 3•(-3)-1= -9-1= -10
f(-2)= 3•(-2)-1 = -6-1 = -7
f(1)= 3•1-1= 3-1= 2
f(0)= 3•0-1=0-1 = -1
f(1) = 3•1-1=3-1 =2

Im f ={-10,-7,-1,2}
