Answer:
Yes.
Step-by-step explanation:
This relation is a function because each input has one and only one output, i.e. 2 yields 1, 4 yields 2, 6 yields 3, 8 yields 4 and 10 has an output of 3. Therefore, it is a function.
If f(x) = {(2, 3), (4, 8), (7, –1)} and g(x) = {(8, 2), (–1, 4), (2, 7)}, find (f ◦ g)(x), if it exists.

Answer:
(f o g )(x) = {8, 3), (-1, 8), (2, -1)}
Step-by-step explanation:
(f o g)(x) = [f(g(x)]
g(8) = 2 and f(2) = 3
g(-1) = 4 and f(4) = 8
g(2) = 7 and f(7) = -1
So, (f o g )(x) = {8, 3), (-1, 8), (2, -1)}

The first one
Step-by-step explanation:
You can't use AAA to prove two triangles congruent because triangles can have the same measures of all its angles but be bigger or smaller, AAA could probably <span>be used to prove two triangles are similar not congruent.</span>
