To analyze an equation of a parabola their special characteristics that can be looked at to determine what type of parabola it is.
4a = 8
a = 2
Since nothing is being added to the constant
8x then the vertex is located at
(0,0). The focus is located at
(a,0) which is
(2,0). The directrix is located at
x = -2.
Now the last part remaining is to solve for two points on the graph, let's use the focus value of
a to determine those points.
Now the values for graph are.
Now the easy part is to graph it!
