Make a table of values and connect the points with a parabola.

Graph:

Practice makes perfect
We want to graph the given quadratic function. y=1/2x^2+2

To do so, we will first make a table of values.

x 1/2x^2+2 y=1/2x^2+2
0 1/2( 0)^2+2 2
2 1/2( 2)^2+2 4
4 1/2( 4)^2+2 10

Note that since the given function has the form y=ax^2+c the axis of symmetry is the vertical line x= 0. Now, let's plot the obtained points and their reflections across the axis of symmetry. Then we can connect them with a parabola.
