Which expression represents the composition [f o g o h](x) for the functions below? f(x) = –2x^4 g(x) = 4x – 6 h(x) = x – 1

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.
