Homework Quiz 5/1:

From the test review:

1. Work and answer to the first 2 problems you completed from the review.

2. Turn in your graph notes and homework from Wednesday and Thursday.(20 points for 1st page, 20 points for 2nd page, 20 points for homework)

PW 10-2 # 1&2

solutions are: {-3} since (x+3)(x+3) are the equation's factors.

solutions are: {2,3} since (x-2)(x-3) are the equation's factors.

Quiz tomorrow:

10 items -

·first 2 are graphing quadratics. Including listing the axis of symmetry, y-intercept and maximum or minimum point.

·next 8 are multiple choice on finding roots, recognizing graph from equation, how the equation shifts up/down, compressed/stretched.
