# How do you graph #y=1/4x^2#?

##### 1 Answer

The axis of symmetry is the line

#### Explanation:

The graph of a quadratic equation is a parabola. Since #a>0, the parabola opens upward. In order to graph the parabola, we need to determine the the axis of symmetry and the vertex. Then determine some additional points.

The axis of symmetry is the line

To determine the

The vertex is

Now determine some other on the parabola by substituting values for

Plot the vertex and the other points. Sketch a parabola through the points, keeping in mind that the graph is a curve. Do not connect the dots.
