You can put this solution on YOUR website!
Determine the vertex of y = x^2 - 8x + 22
\n" ); document.write( ":
\n" ); document.write( "Use the vertex equation: x = -b/(2a)
\n" ); document.write( ":
\n" ); document.write( "This is based on the form: ax^2 + bx + c
\n" ); document.write( ":
\n" ); document.write( "In your equation a = 1, b = -8, c = 22 (not used here)
\n" ); document.write( ":
\n" ); document.write( "x = -(-8)/(2*1)
\n" ); document.write( "x = +8/2
\n" ); document.write( "x = 4 is where the vertex line passes thru and is the x value for the max or the min of the equation. When a is positive it will be min, and when a is negative it will be a max. \n" ); document.write( "
