Consider the simpler equation y = 1/x^2. The line of symmetry is the vertical asymptote x = 0. In our problem the factor 1/(x+2)
^2 displaces the curve y = 1/x^2 2 units to the left. In short, the axis of symmetry of our equation is x = -2. (Note the 1/3 and 5 constants do not impact the axis of symmetry. See attachments, whose y value starts at 5,
The terms 'technology' and 'applied science' will be taken here as synonymous, although neither is adequate: in fact, 'technology' sug- gests the study of practical arts rather than a scientific discipline, and 'applied science' suggests the application of scientific ideas rather than that of the scientific method
