Question

Make a scatter plot of the data below.V25150175100125150178216265323150175392470.4a.Use the quadratic regression feature of a graphing calculator to find a quadratic model. Round to the nearestthousdandths place.y = 7.821x2 - 0.936x - 94.034b.y = -7.8217+0.936x - 94.034y = 0.008x2 + 0.518x + 131.886d. y = 0.008x2 - 0.518x - 131.886C.

Answer 1

The scatter plot of the given data is the following:

Where the horizontal is x values and the vertical is y values. The blue points are the locations of the given data.

Using a statistical program like excel, or a graphic calculator like the problem states, we can find the quadratic regression model.

I will use the program "statgraphics" to do this:
