f(x) = x² + 1, x > 0
y = x² + 1
x = y² + 1
x - 1 = y²
√x - 1 = y
√x - 1 = f(x), x > 1

The answer to your question is software.
So, this is an answer of your choice. What it is trying to ask is tell us what your dream home, job, husband, and so on. For example: My dream home is a mansion in Mississippi by the beach. My dream job is a doctor. Those are prime examples of a dream home and job. Now your answer shouldn't be the same as mine. Your's should be something different. Unless, you want a mansion in Mississippi by the beach and you would like to be a doctor. In other words it is asking you to tell us what you want you home, lifestyle, job, friends, and possibly your DREAM pet. Hope this helps.
