• Degree: 7, Leading Coefficient: 10

• Degree: 3, Leading Coefficient: -5
• Degree: 10, Leading Coefficient: -7
• Degree: 5, Leading Coefficient: -100

• Degree: 6, Leading Coefficient: -1/25
• Degree: 5, Leading Coefficient: -1/36
• Degree: 4, Leading Coefficient: 1/25
• Degree: 3, Leading Coefficient: -1/18

• f(-5) = 9(-5)^3 - 4(-5)^2 + 5(-5) + 7 = -1125 - 100 - 25 + 7 = -1200

• f(-5) = 9(-5)^3 - 4(-5)^2 + 5(-5) + 7 = -1125 - 100 - 25 + 7 = -1233

• f(-5) = 9(-5)^3 - 4(-5)^2 + 5(-5) + 7 = 9(-125) - 4(25) - 25 + 7 = -1125 - 100 - 25 + 7 = -1243

• f(-5) = 9(-5)^3 - 4(-5)^2 + 5(-5) + 7 = -1125 - 100 - 25 + 7 = -1153

• 100a² + 10

• 25a²+ 20

• 10a² + 20

• 100a² + 20
