[tex]\begin{gathered} y_1=x^2+1 \\ y_2=\frac{x^2}{2}+1 \end{gathered}[/tex]
Both equations are symmetrical when related to the y-axis and have a vertex at (0,1). But, since coefficient 1/2 make the second equation grows slower, we can conclude that the graph of the first equation is narrower than the graph of the second equation.
