Find the quadratic equation for the relationship of the horizontal distance and the height of the ball.

• f(x) = -18x² + 2.11x + 4.21

• f(x) = -.06x² +1.06x + 7.9

• f(x) = -6x² +1.06x + 79

• f(x) = -.12x² + 2.11x + 4.22

A scientist observes the weight, y, of a 100-gram sample decay every week, x. Determine which exponential regression best models the data in the table.

• y = 100(8.7)^x

• y = 100(1.87)^x

• y = 100(.87)^x
