Question

Pentru functiile de mai jos calculatii valorile cerute! f:R-R f(x)=7x-8 ...f(1),f(2),f(7),f(9),f(0),f(-1),f(-3),f(1supra7),f(3supra2) Va Roog mult!!!

Answer 1

f(1)=7×1-8
f(1)=7-8
f(1)=-1

f(2)=7×2-8
f(2)=14-8
f(2)=6

f(7)=7×7-8
f(7)=49-8
f(7)=41

f(9)=7×9-8
f(9)=63-8
f(9)=55

f(0)=7×0-8
f(0)=-8

f(-1)=7×(-1)-8
f(-1)=-7-8
f(-1)=-15

f(-3)=7×(-3)-8
f(-3)=-21-8
f(-3)=-29

f(1/7)=7×1/7-8
f(1/7)=1-8
f(1/7)=-7

f(3/2)=7×3/2-8
f(3/2)=21/2-8
f(3/2)=21-16
f(3/2)=5
