Question

Let f = {(–2, 4), (–1, 2), (0, 0), (1, –2), (2, –5)}.

Let g = {(–3, 3), (–1, 1), (0, –3), (1, –4), (3, –6)}.

What is g(f(2))?

-5

-1

2

The composition is undefined.

Answer 2

@ZombieSlayer:

start with f(2). look at the f function, find the corresponding y-value for x = 2

now, moving onto g(f(2)), take the y-value from f(2). this becomes your new x-value for g(x). find the corresponding y-value for g(x).
