Which statement is correct about the transformation of a function f(x)? a. By moving f(x) k units down, you obtain the function f(x)+k.
b. By moving f(x) k units to the right, you obtain the function f(x−k).
c. By shrinking f(x) k units horizontally, you obtain the function 1kf(x).
d. By stretching f(x) k units vertically, you obtain the function f(kx).
