Se considera functia f: R ---> R, f(x)=√2 inmultit x+1
Calculeaza media aritmetica a numerelor f(1) si f (-1)
Calculati media geometrica a numerelor f (√2) si f(13√2)

f(1)=radical2 + 1
f(-1)=-radical2 +1
Ma=1
f(radical2)=3
f(13radical2)=27
Mg=radical71
f(1)=[tex] \sqrt{2}+1 [/tex]
f(-1)=[tex]- \sqrt{2}+1[/tex]
ma=[tex] \frac{ \sqrt{2}+1+ (-\sqrt{2})+1}{2} = \frac{2}{2}=1 [/tex]
[tex]f( \sqrt{2})=3 [/tex]
[tex]f(13 \sqrt{2})=27[/tex]
[tex]mg= \sqrt{3*27}= \sqrt{81}=9 [/tex]
