va rog e urgent pe lund macar 1 ex. varog​

Answer 1

Răspuns:

a)F(-3)=10-(-3)²/-3=10-9/-3= -1/3

F(-2)=10-(-2)²/-2=10-4/-2=6/-2= -3

F(-1)=10-(-1)²/-1=10-1/-1=9/-1=-9

F(1)=10-1²/1=9/1=9

F(2)=10-2²/2=10-4/2=6/2=3

F(3)=10-3²/3=10-9/3=1/3

Le ordonam crescator: -9,-3,-1/3,1/3,3,9

Raspuns: F(-1), F(-2), F(-3), F(3), F(2), F(1)

b) F(-4)=10-(-4)²/-4=10-16/-4= -6/-4=3/2

F(4)=10-4²/4=10-16/4=-6/4= -3/2

F(-0.5)=F(-1/2)=10-1/4 /-1/2=39/4/-1/2=39/4X(-2)= -39/2

F(0.5)=10-1/4/1/2=39/4x2=39/2

Le ordonam descrescator: F(0.5), F(-4), F(4), F(-0.5)

Answer 2

$\it F(-3)=\dfrac{10-9}{-3}=-\dfrac{1}{3} \\ \\ \\ F(-2)=\dfrac{10-4}{-2}=-\dfrac{6}{2} =-3\\ \\ \\ F(-1)=\dfrac{10-1}{-1}=-\dfrac{9}{1} =-9\\ \\ \\ F(1)=\dfrac{10-1}{1}=\dfrac{9}{1} =9\\ \\ \\  F(2)=\dfrac{10-4}{2}=\dfrac{6}{2} =3\\ \\ \\ -9<-3<-\dfrac{1}{3}<3<9$
