Example 1 - no calculation required
The shift of the vertex (right, left, up, down) from (0, 0) can be determine by looking at the graph. Match this shift to the vertex in the answer choices.
Example 2 - mental math
Look at the values of f(x) from the table for the two values of x. -2 subtracted from -1 is -3. Absolute value is always positive = 3.
