Observe the table:

The minimum point is .

Graph:

Graph the function and plot the minimum point .

Observe the graph:

The graph is the same shape as , but the graph is vertically stretched by a factor and translated unit right from origin.

From the graph the minimum point is at , and increases, increases.

The domain of the function , and range of the function is .
