Step-by-step explanation:
The domain is the span of x-values covered by the graph.
From the graph, we can see that the x-values covered by the graph is all values to the left of zero including zero.
Therefore, the domain is all x-values less than or equal to 0:

In interval notation, this is:
![(-\infty,0]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C0%5D)

Answer:
l=200 yard
w=70 yard
Step-by-step explanation:
let width =w
length l=2w+60
then perimeter P=2(l+w)=2(2w+60+w)=540
3w+60=270
3 w=270-60=210
w=70
l=2*70+60=200
