1.Express the Quadratic Function in Standard Form.
\n" ); document.write( "2.Find it's Vertex and its x- and y- intercept(s).
\n" ); document.write( "Standard form of equation: \"y=A%28x-h%29%5E2%2Bk\", (h,k)=(x,y) coordinates of the vertex, A is a coefficient that affects the slope or steepness of the curve
\n" ); document.write( "f(x)=2x^2+4x+3
\n" ); document.write( "complete the square
\n" ); document.write( "f(x)=2(x^2+2x+1)-2+3
\n" ); document.write( "\"f%28x%29=2%28x%2B1%29%5E2%2B1\"
\n" ); document.write( "vertex(-1,1)
\n" ); document.write( "..
\n" ); document.write( "y-intercept
\n" ); document.write( "set x=0
\n" ); document.write( "y=2x^2+4x+3
\n" ); document.write( "y=3
\n" ); document.write( "..
\n" ); document.write( "x-intercept
\n" ); document.write( "set y=0
\n" ); document.write( "0≠2x^2+4x+3
\n" ); document.write( "x-intercept: none\r
\n" ); document.write( "\n" ); document.write( "see graph below as a visual check:
