These are some Rules for the transformations of a function f(x):
a. If the function is shifted left "h" units, then:
b. If the function is shifted right "h" units:
c. If the function is shifted up "h" units:
d. If it is shifted down "h" units:
Notice that the red graph is this function:
And both have the same shape, but the blue one is moved to the left 2 units. Therefore the equation of the blue graph is:
THE ANSWER IS OPTION A.
