are you thinking of y=a x^2 + b if a is varied, the "dialation" is obvious. Here is a another shape reflected on the y axis (and x axis) by+^2+ax^2= c^2 the ellipse.

A microscope shows you an image of an object that is 80 times the actual size. Therefore, the scale factor of the enlargement is 80. An insect has a body length of 7 millimeters. What is the body length of the insect under the microscope? I know it's 560, but not sure if ...
