Identify the type of function from the table.

• linear

• quadratic

• exponential

• absolute value

The quadratic equation that can produce this table is what?

• f(x) = 4x² + 4

• f(x) = -4x² - 4

• f(x) = 4x² - 4

• f(x) = -4x² + 4

Given the table, determine the equation of the function.

• y = (x+3)² + 8

• y = -(x+3)² + 8

• y = (x-3)² + 8

• y = -(x-3)² - 8
