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

Graph:

Practice makes perfect
We want to graph the given quadratic function. f(x)=x^2+4

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

x x^2+4 f(x)=x^2+4
0 0^2+4 4
2 2^2+4 8
4 4^2+4 20

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.
