Question

Construa o gráfico da função y= x ao quadrado+1, usando para x os valores -2, -1, 0, 1, 2.

Answer 1

$y=x^2+1 \\ \\ X~~~|~Y \\ -2~|~5~~\mapsto(-2)^2+1=4+1=5 \\ -1~|~2~~\mapsto(-1)^1+1=1+1=2 \\ ~~~0~~|~1~~\mapsto0^2+1=1 \\ ~~~1~~|~~2~~\mapsto1^2+1=1+1=2 \\ ~~~2~~|~~~5~~\mapsto2^2+1=4+1=5$
