The equation for a parabola with directrix y = –p and focus (0, p)
The distance between vertex and directrix is P
Also the distance between vertex and focus is also P
Focus (0,p) so focus lies on y axis
Directrix line is paralled to focus point
So Directex crosses the x axis .
Hence line of symmetry lies is the y-axis.
The graph is attached below.

Answer:
6
Step-by-step explanation:
2(x+2) + 3x
2x + 4 + 3x = 34
5x + 4 = 34
5x = 34–4
5x = 30
x = 30/5
x = 6
