document.write( "Okay, I did this problem by hand and simplified the equation down to -2x^2+4x-7 using order of operations; I squared x-1, multplied the answer by -2, and subtracted 3 from that answer. Then I tried using the quadratic formula, but it didn't turn out. So I graphed my simplified equation (-2x^2+4x-7) and came up with an upside-down hyperbola with the max point at -5. Is this my answer? And if it is, how do I show my work for this since I used my calculator to graph?\r<BR>\n" );
