Use the graph of the function to find, f(2).
2
-1
-2
1

f(2) =1

Step-by-step explanation:

f(2) means find the value of the function when x= 2

The y value of the function is 1 when x=2

f(2) =1

robert puts 2 in each row

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.
