Which expression is equivalent to 3m+1-m? a. 3m b. 3m-1 c. 1+3 d. 2+m-1+m

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)
