To change the shape of a function, you need to or compress it.

a. compress
b. stretch
c. shift
d. flip

Answer – B. Stretch
 Transformations are said to be rigid if they maintain the same size and shape, so by inference, a change in shape can only be accomplished by a non-rigid transformation. A form of non-rigid transformation is a stretch or compression therefore, in order to change the shape of a function, you need to stretch or compress it.
