Front

What is the general form of a square root function?

Back

The general form is @@f(x)= ext{sqrt}(x-h)+k@@, where (h,k) is the vertex.

Front

How does the value of h affect the graph of the square root function?

Back

The value of h shifts the graph horizontally; if h is positive, the graph shifts right.

Front

How does the value of k affect the graph of the square root function?

Back

The value of k shifts the graph vertically; if k is positive, the graph shifts up.
