1. Find the maximum or minimum of the following quadratic function: y =x^2 - 10x + 25.
\n" ); document.write( "2. Find the maximum or minimum of the following quadratic function: y =x^2 - 2x - 48.
\n" ); document.write( "3. Find the maximum or minimum of the following quadratic function: y = x^2 - x - 56.
\n" ); document.write( "4. Find the maximum or minimum of the following quadratic function: y = 16x^2+ 40x + 25.
\n" ); document.write( "5. Find the maximum or minimum of the following quadratic function: y = x^2 - 16.
\n" ); document.write( "**
\n" ); document.write( "All the problems above require the same method (completing the square) to solve.
\n" ); document.write( "Standard form of equation for the problems: y=A(x-h)^2+k, (h,k)=(x,y) coordinates of the vertex.
\n" ); document.write( "If the lead coefficient is >0, parabola open up, and has a minimum. If lead coefficient <0, parabola open down, and has a maximum. The x-term of the vertex is the maximum or minimum value.
\n" ); document.write( "I will do the first 2, and let you do the rest.
\n" ); document.write( "..
\n" ); document.write( "1) y =x^2 - 10x + 25
\n" ); document.write( "completing the square
\n" ); document.write( "y =(x^2-10x+25)-25 + 25
\n" ); document.write( "y=(x-5)^2+0
\n" ); document.write( "vertex: (5,0)
\n" ); document.write( "minimum=0
\n" ); document.write( "..
\n" ); document.write( "2) y =x^2 - 2x - 48
\n" ); document.write( "completing the square
\n" ); document.write( "y =(x^2-2x+1)-1-48
\n" ); document.write( "y=(x-1)^2-49
\n" ); document.write( "vertex: (1,-49)
