Does the vertex of the graph of

f(x) = -2(x + 5)² + 2

contain a minimum or a maximum?

• Minimum

• Maximum

• It has neither.

• It has both.

Identify the minimum or maximum value and the domain of the function y = -2(x+1)² + 4

• Max: 4, Domain: All Real Numbers

• Min: -4, Domain: All Real Numbers

• Max: 2, Domain: All real numbers greater than 4

• Min: -2, Domain: All real numbers less than 4

• x = 2; (2 , -8) 

• x = -2; (-2 , -8) 

• x = -2; (-2 , 8) 

• x = 2; (2 , 8) 

• y = 9x² - 15x + 21

• y = -3x² - 75x - 4

• y = 9x² + 90x + 221

• y = -3x² - 30x - 79
