Given the following scatter plot, which equation best models the data? (Hint: in this specific case, you don't really need Desmos)

• y = -8.25x + 56

• y = -8.25x² + 56x

• y = 8.25x² + 56x

• y = -8.25x³ + 56x

Using the quadratic curve of best fit, find the height of the ball when it traveled a distance of 10 feet.

• quadratic

• cubic

• exponential

• y = 1.45x + 22
• y = -2x + 15
• y = 1.33x + 30
• y = -1.5x + 24

Using the curve of best fit, what would be the output (y) when the input (x) is 7?

• 260

• 240
