What are the zeros of the function?

Zero function is when y = 0 or f(x) = 0

So look at the graph when y = 0, x = -2 and x = 4

Answer is the first one

-2 and 4

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.
