Unit 8 Lesson 3 Finding Roots Graphically

What are the x- intercepts?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

• Yes, since the x intercepts are at -2 and 3

• Yes, since the x intercepts are at -3 and 2

• No, since the x intercepts are at -3 and 2

• No, since the x intercepts are at -2 and 3
