y= 1/2(x -5)^2 - 3
\n" ); document.write( "A write the equation in standard form
\n" ); document.write( "b Write the equation in intercept form
\n" ); document.write( "---
\n" ); document.write( "Form:: y = a(x-b)(x-c)
\n" ); document.write( "----------------------
\n" ); document.write( "y = (1/2)(x^2-10x+25) - 3
\n" ); document.write( "I graphed it and found x-intercepts at x = 2.55 and 7.45
\n" ); document.write( "----
\n" ); document.write( "y = a(x-2.55)(x-7.45)
\n" ); document.write( "----
\n" ); document.write( "Solve for \"a\" using the y-intercept
\n" ); document.write( "y-intercept:
\n" ); document.write( "y = (1/2)(0-5)^2-3
\n" ); document.write( "y = 12.5-3 = 9.5
\n" ); document.write( "------
\n" ); document.write( "y-intercept = (0,9.5)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"a\":
\n" ); document.write( "9.5 = a(-2.55)(-7.45)
\n" ); document.write( "a = 0.5
\n" ); document.write( "---
\n" ); document.write( "Intercept Form::
\n" ); document.write( "y = 0.5(x-2.55)(x-7.45)
\n" ); document.write( "----------------
