\n" ); document.write( ": I'm in Chapter 6 section 6. Its about Alalyzing Graphs of Quadratic Functions. the problem looks like this: y=5x(squared) -6
\n" ); document.write( "my question is when you write the quadratic funcionin vertex form, do you factor out a 5 and just have your x*x remaining and then subtract 6, or do you have x*x squared? \n" ); document.write( "

Vertex form is $\"highlight%28y=a%28x-h%29%5E2%2Bk%29\"$ , the vertex is (h,k)
\n" ); document.write( "Notice that x doesn't have a coefficient inside the parenthesis, if x^2 has a coefficient you factor, then complete the square. This one is different because a isn't 1 and there's no b.
\n" ); document.write( " $\"y=5x%5E2-6\"$
\n" ); document.write( " $\"y=5%28x-0%29%5E2-6\"$ is vertex form, the vertex is (0,-6), because a>1 the parabola is skinnier.
