Question

podstaw za x do wzoru i olicz.

y=1\4(x-2)[2]+1

do liczb 0,1,-1,2.-2,3,-3.

to co w nawiasie kwadratowym[2] to do kwadratu

Answer 1

y=1/4(x-2)^2 +1

 

f(0)=1/4*(0-2)^2+1=1/4*(-2)^2+1=1/4*4+1=1+1=2

 

f(1)=1/4*(1-2)^2+1=1/4*(-1)^2+1=1/4*1+1=1  1/4

 

f(-1)=1/4*(-1-2)^2+1=1/4*(-3)^2+1=1/4*9 +1=

=9/4 + 4/4=13/4=3  1/4

 

f(2)=1/4*(2-2)^2+1=1/4*0+1=1

 

f(-2)=1/4*(-2-2)^2+1=1/4*(-4)^2+1=1/4*16+1=

=4+1=5

 

f(3)=1/4*(3-2)^2+1=1/4*1+1=1/4+1=1  1/4

 

f(-3)=1/4*(-3-2)^2+1=1/4*(-5)^2+1=

=1/4*25 + 4/4 = 29/4=7  1/4
