Given
Answer
The graph touches the x-axis at -6
Hence x = -6 is the zero of the graph.
Answer:
1 2/4
Step-by-step explanation:
3/4 doubled is 
Now,
on simplification.

Therefore,
3/4 doubled is 1 2/4
Reflection, across the y axis
Answer:
Area = length x width
width = 1/2 length = 12/2 = 6 = width
area = 6x 12 = 72
