g (0) =
g (1) =
g (2) =
g (3) =
b) dla x € {1,2,5,10}
f (1) =
f (2) =
f (5) =
f (10) =
2. oblicz f(-2), , jeżeli

2.
a)
f(-2)= 2√2
f(√3)= √7
b)
f(-2)=22
f(√3)=7-6√3
c)
f(-2)=2
f(√3)=1
a) g(x) = 3x^{2} dla x € {0,1,2,3}
g (0) =3*0=0
g (1) =3*1=3
g (2) =3*4=12
g (3) =3*9=27
x | 0 | 1| 2 | 3 |
y | 0 | 3| 12| 27|
b) dla x € {1,2,5,10}
f (1) =√0=0
f (2) =√1=1
f (5) =√4=2
f (10) =√9=3
x | 0 | 2| 5 | 10 |
y | 0 | 1| 2 | 3 |
2. oblicz f(-2), , jeżeli
a) f (x) =
f(-2)=√(4+4)=√8
=√(3+4)=√7
b) f (x) = 3x^{2} - 6x - 2
f(-2)=3*4+12-2=22
f(√3)=3*3-6√3-2=7-6√3
c)
f(-2)=-3+4+1=2
f(√3)=6/√3-2√3+1=2√3-2√3+1=1
