This question is very very difficult for me. i would really like some or any that i can get . the question is in the attachtment!

y do u put "subscirbe to ence" on a app for ppl who need with their work?

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
