The function f(x)=2x^2+12x+32 models the approximate height of an object t seconds after it is launched. How many seconds does it take the object to hit the ground?
\n" ); document.write( "-----------
\n" ); document.write( "The function is in x, not t.
\n" ); document.write( "---
\n" ); document.write( "If it's f(t):
\n" ); document.write( "f(t) = 2t^2 + 12t + 32
\n" ); document.write( "it will never \"hit the ground,\" that is, f(t) will never = zero (0).
\n" ); document.write( "f(0) = 32, and it increases with t.
\n" ); document.write( "It's a real rocket (tho not a good function), not a projectile.
\n" ); document.write( " \n" ); document.write( "

\n" );
