Question 1202227
.


They want you compare the plot y = (2x)^2 with the plot of the parent function y= x^2.



        There are  TWO  EQUIVALENT  descriptions of this transformation.



One description says that the plot is  COMPRESSED horizontally  with the coefficient of  2.


The other description says that the plot is  STRETCHED  vertically with coefficient of  4.


For given problem,  both these descriptions are  EQUIVALENT,  as I just said above.


They are equivalent, because the function has two equivalent presentations


              y = (2x)^2 = 4*x^2.
