if XY = PQ and YZ = QR,

what additional info is needed to prove the triangles congruent?

• ∠Z ≅ ∠R

• ∠X ≅ ∠P

• ∠Y ≅ ∠Q

• No additional information is needed.

Which function is graphed?

Which statement identifies the effect of

replacing the graph of f(x) with 2f(x) on the graph?

• The curve would be narrower, but the vertex would stay in the same position

• The curve would be wider, but the vertex would stay in the same position

• The curve would remain the same position, but be flipped upside down.

• The curve would remain the same position, but be shifted 2 units right.

Which statement identifies the effect of

replacing the graph of f(x) with ⅓f(x) on the graph?

• The curve would be narrower, but the vertex would stay in the same position

• The curve would be wider, but the vertex would stay in the same position

• The curve would remain the same position, but be flipped upside down.

• The curve would remain the same position, but be shifted 2 units right.

• f(x) has the

  greater minimum of 5.

• g(x) has the

  greater minimum of 3.
