Determine the equation of the parabola, in vertax form, with:
\n" ); document.write( "a) vertex (-1,-3) that passes through the point (5,8)
\n" ); document.write( "Form: (x-h)^2 = 4p(y-k)
\n" ); document.write( "h=-1, k=-3, and y=8 when x=5; solve for p
\n" ); document.write( "(5+1)^2 = 4p(8+3)
\n" ); document.write( "36 = 4p(11)
\n" ); document.write( "4p = 36/11
\n" ); document.write( "---------
\n" ); document.write( "Equation: (x+1)^2 = (9/11)(y+3)
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "b) vertex (-4,3) and a y-intercept of 7.
\n" ); document.write( "intercept is the point (0,7)
\n" ); document.write( "(0+4)^2 = 4p(3-7)
\n" ); document.write( "16 = 4p(-4)
\n" ); document.write( "4p = -4
\n" ); document.write( "-------------
\n" ); document.write( "(x+4)^2 =-4(y-3)
\n" ); document.write( "=====================
