Recall that the word sum indicates addition. write the numerical expression that is equivalent to the following phrase:
the sum of -3 and - 5 increased by 2.

now simplify the expression and give the final result:

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)
