Question

For which pair of functions is mc004-1.jpg?
f(a) = a2 – 4 and mc004-2.jpg
mc004-3.jpg and g(a) = 2a – 2
f(a) = 5 + a2 and mc004-4.jpg
f(a) = 3 – 3a and g(a) = 4a – 5

Answer 1

I don't have the images (mc004-1.jpg, etc.), so I can't see the missing functions or the exact question. Could you either

- upload the images, or
- retype the full problem and all four answer choices (write each function explicitly),

and tell me what property you're being asked about (for example: “which pair are inverses?”, “which pair are equal?”, “which pair are compositions that equal x?”, etc.)?

If you meant “which pair are inverse functions?”, I can check quickly — tell me the missing functions or upload the images and I’ll test f(g(x)) = x and g(f(x)) = x for each pair.
