Verify 4/5 + ( 3/9 + 2/3 ) = ( 4/5 +3/9 ) + 2/3

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)
