Which of these functions is a transformation of the function f(x)=3^x where the function is translated 2 units to the right and horizontally stretched by a factor of 4

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
