Question

Show, step by step, how you can make the reverse process of putting
y = x^2010x + 5 into the form y = (x - 5)2 + 20.

Answer 1

Answer:

hope this helps you

Step-by-step explanation:

You can see that the original guess (20 inches or so) was way off. For 2015, it looks like the line will be somewhere between 5 and 10 inches! That might be “good enough”, but regression also gives you a useful equation, which for this chart is:

y = -2.2923x + 4624.4.

What that means is you can plug in an x value (the year) and get a pretty good estimate of snowfall for any year. For example, 2005:

y = -2.2923(2005) + 4624.4 = 28.3385 inches, which is pretty close to the actual figure of 30 inches for that year.
