What are the domain and range of the function?

domain: {-2, -1, 0, 1, 2}

range: {0, 2, -4, -8}

Step-by-step explanation:

The domain is a set of all the x-values in the graph. This is made up of:

{-2, -1, 0, 1, 2}

The range is made up of all the y-values(no repeats):

{0, 2, -4, -8}

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.
