For the graph of the function below, identify the axis of symmetry, vertex and the formula for the function.

a. axis of symmetry: x = –1; vertex: (–1, 0); f(x) = –x2 – x + 2

b. axis of symmetry: x = –1; vertex: (–1, 0); f(x) = –2x2 – 2x – 1

c. axis of symmetry: x = –1; vertex: (–1, 0); f(x) = –x2 – 2x – 1

d. axis of symmetry: x = –1; vertex: (–1, –1); f(x) = –x2 – 2x – 1

Aadc is formed by reflecting aabc across line segment ac, as shown in the figure. if the length of ac is 4 units, the area of aadc is square units.

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
