If the function is translated 4 units down, the resulting function will be
y = x - 4 while the vertical stretch by 3units will be y = 3(x-4)
Transformation of functions
Transformation of function is a way of changing the position of a line or curve on an xy place.
Given the equation of a line as shown;
y = x (This will serve as the parent function)
If the function is translated 4 units down, the resulting function will be
y = x - 4. If the resulting function is stretched by a factor of 3, the final function will be y = 3(x - 4)
