A county real estate appraiser wants to develop a statistical model to predict the appraised value of houses in a section of the county called East Meadow. One of the many variables thought to be an important predictor of appraised value is the number of rooms in the house. Consequently, the appraiser decided to fit the linear regression model E(y)equalsbeta 0plusbeta 1x, where y equals the appraised value of the house (in thousands of dollars) and x equals the number of rooms. Using data collected for a sample of nequals107 houses in East Meadow, the following result was obtained. ModifyingAbove y with caretequals74.80plus19.72x What are the properties of the least squares line, ModifyingAbove y with caretequals74.80plus19.72x?

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
