Identify which shapes on the graph are congruent to shape i by performing these sequences of transformations on shape i:
• a reflection across the y-axis, followed by a 90° counterclockwise rotation about the origin, and then a translation 3 unite down
• a 90° clockwise rotation about the origin and then a translation 2 units up and 2 unite left
• a 180° rotation about the origin and then a translation 1 unit right

The base of a triangle exceeds the height by 9 inches. if the area is 180 square inches, find the length of the base and the height of the triangle.

What is the value of f(x) = 2.2 for f(-2)?
