What is the domain and range as an inequality and if you could explain how you got it that would be great

As per the graph, the function starts at point (0, -2) point it self not included.

The graph is extended down and right, so the given point is maximum of the function.

The domain:

The range:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
