See answer below

Given: $y = x^{2} + 1$ $y = x^2 + 1$

This function is a quadratic (square function). When graphed we call this function a parabola.

Graph using point plotting. Since $x$ $x$ is the independent variable we can select any $x$ $x$ and calculate the corresponding $y$ $y$ .

$ul(" "x " "|""-3" "|""-2" "|""-1" "|" "0" "|" "1" "|" "2" "|" "3" "|)$
$" "y" "|" "10" "|" "5" "|" "2" "|" "1" "|" "2" "|" "5" "|" "10" "|$

Graph of $y = x^2 + 1$ :

graph{y = x^2 + 1 [-5, 5, -5, 10]}
