Determine the curve of best fit.

• y = -2.7x + 7.4

• y = 0.95x² - 2.08x - 0.75

• y = -.05x - 3.26

• y = 0.95x² + 2.08x + 0.75

Find the quadratic equation for the relationship of the horizontal distance and the height of the ball. Answers may be rounded to the hundredth.

• y= -0.11x² + 2.11x + 4.21

• y= 2.11x² +4.22x - 0.12

• y=4.22x² -0.12x + 2.11

• y= -0.12x² + 2.11x + 4.22

A person travels by car. They record their miles driven in a data table. Calculate the linear regression equation of this data. Answers may be rounded to the nearest hundredth.

• y = 61.93x - 1.79

• y = -1.79x + 61.93

• y = 61.92x + 1.79

• y = 61.92x -1.78

Which type of regression model does the scatter plot appear to show?

• linear

• exponential

• quadratic

Use the exponential regression to find an equation that fits the​ data, where x is the years since 1990.

• y=8.92•1.23^x
• y=1.23•8.92^x
• y=8.92+1.23x
• y=8.92x+1.23
