The rule as a mapping for the translation of a rectangle is (x, y) → (x – 2, y + 7). which describes this translation?

answer: a.   one is a factor of every whole number since every number is divisible by itself.

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)
