What is the correct equation?

The graph shows one of the six basic functions and a transformation of the function. Describe the transformation. 5 3 2 X 1 2 3 5 6 O The transformation is a vertical shift 3 units downward of the basic function. O The transformation is a horizontal stretch by a factor of 3 of the basic function. The transformation is a horizontal shift 3 units to the left of the basic function. The transformation is a vertical shift 3 units upward of the basic function. O The transformation is a horizontal shift 3 units to the right of the basic function. Use your description to write an equation for the transformation. y(x) = x-3- X
