find the vertex, the line of symmetry and the maximum or minimum value of f(x). Graph the function
\n" ); document.write( "f(x)=1/2(x+3)^2+3?
\n" ); document.write( "----
\n" ); document.write( "Your equation IS in vertex form:
\n" ); document.write( "y = a(x-h)^2+k
\n" ); document.write( "---
\n" ); document.write( "The vertex is (h,k)
\n" ); document.write( "-h = 3
\n" ); document.write( "h = -3
\n" ); document.write( "k = 3
\n" ); document.write( "----
\n" ); document.write( "Vertex is (-3,3)
\n" ); document.write( "----------
\n" ); document.write( "Since the coefficient of (x+3) is positive
\n" ); document.write( "the parabola opens UP.
\n" ); document.write( "---
\n" ); document.write( "The line of symmetry is a vertical line passing
\n" ); document.write( "through the vertex.
\n" ); document.write( "Therefore its equation is x = -3
\n" ); document.write( "--------------------------------------
\n" ); document.write( "\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C%281%2F2%29%28x%2B3%29%5E2%2B3%29\"
\n" ); document.write( "============================

\n" ); document.write( "Therefore the vertex is at a minimum point.
