• x: -4 and -2; y: -8

• x: -8 and -2; y: -4

• x: 4 and 2; y: 8

• x: -1 and 3; y -8

In order to demonstrate your understanding of quadratic functions. you will find real life images of parabolas.

• Great! I cannot wait for another project.

• At least it is better than practice problems.

• Wait, I still don't understand the concepts.

• Where is my rubric? When is it due?

Identify the x-intercepts for the quadratic function y = 2x²-8x+10

• 10 and 2

• There is only one at 2

• -2 and 10

• Wait, there are no x- intercepts
