Features of Graphs of Functions

• Shifts the function up 2 units.

• Shifts the function down 2 units.

• Shifts the function left 2 units.

• Shifts the function right 2 units.

Answer explanation

The +2 in the function shifts the graph left 2 units, as it affects the x-value by moving it horizontally.

Determine the domain of the graph.

• (1, +∞)

• [1, +∞)

• (2, +∞)
