The table shows the population of a town from 1996 to 2004. Assume that t is the number of years since 1996 and P is measured in thousands of people.
Which of the following is the model that best fits the data rounded to the nearest tenth?

Use the results of the regression shown to predict the population in 2007.

What value of x will you be plugging into your equation??

Using the regression equation rounded to TWO decimal places, what would be the estimated population for the year 2007? *Your answer should be a whole number in the thousands!

Determine the curve of best fit.

The equation of the parabola that best fits a set of data is called

• quadratic formula

• quadratic regression

• quadratic standard form

• quadratic function

How high was the ball when it was initially (first) thrown? Choose the best answer.

• 0 feet because this is the y-intercept.

• 3 feet because this is the y-intercept.

• 4 seconds because this is the axis of symmetry.

• 5 feet because this is the y-value of the vertex (highest point).
