Which function would best represent each ink cartridge purchased for a printer costs $12.

• Linear

• Quadratic

• Exponential

Which model is appropriate given the points (-3, 8), (-1, 6), (0, 5), (2, 3), (3, 2)? Why?

• Exponential because it curves.

• Linear because it has a constant slope.

• Quadratic because it has a minimum.

• Infinite because it keeps going.

Choose all the equations that are exponential:

• y = 6x -5

• y = 8^x - 9

• f(x) = 3x² + 4

• y = 1/3^x

• y = 7x³

Write the function that best models the table?

• y = (1/4)x

• y = 4x

• y = 4^x

• y = (1/4)^x
