Find the x and y intercepts of the parabola.
\n" ); document.write( "y = \"-3%28x+%2B+4%29%5E2+%2B+27\"
\n" ); document.write( "***
\n" ); document.write( "y-intercept:
\n" ); document.write( "set x=0
\n" ); document.write( "y=-3*4^2+27=-48+27=-21
\n" ); document.write( "...
\n" ); document.write( "x-intercept:
\n" ); document.write( "set y=0
\n" ); document.write( "-3(x+4)^2+27=0
\n" ); document.write( "(x+4)^2=-27/-3=9
\n" ); document.write( "(x+4)^2=9
\n" ); document.write( "take sqrt of both sides:
