Graph Y=3x^2-8x+2 and give the vertex, domain and range?\r
\n" ); document.write( "\n" ); document.write( "The y-intercept happens when x=0
\n" ); document.write( "y=3(0)^2-8(0)+2
\n" ); document.write( "y=0-0+2
\n" ); document.write( "y=2 Plot (0,2)
\n" ); document.write( ":
\n" ); document.write( "The quadratic equation is in standard form \"y=ax%5E2%2Bbx%2Bc\"
\n" ); document.write( "a=3, b=-8, and c=2
\n" ); document.write( "Because a is positive, the parabola opens upward.
\n" ); document.write( "The x coordinate of the vertex is found with the formula \"x=-b%2F2a\"
\n" ); document.write( "\"x=-%28-8%29%2F%282%283%29%29\"
\n" ); document.write( "\"x=8%2F6\"
\n" ); document.write( "\"x=4%2F3\"
\n" ); document.write( "Substitute that into the equation to find the y coordinate.
\n" ); document.write( "\"y=3%284%2F3%29%5E2-8%284%2F3%29%2B2\"
\n" ); document.write( "\"y=3%2816%2F9%29-32%2F3%2B2\"
\n" ); document.write( "\"y=16%2F3-32%2F3%2B2\"
\n" ); document.write( "\"y=16%2F3-32%2F3%2B6%2F3\"
\n" ); document.write( "\"y=-10%2F3\"
\n" ); document.write( "The vertex is (4/3,-10/3)
\n" ); document.write( "The domain for all parabolas is all real numbers. {x|x=R}
\n" ); document.write( "The range is from the vertex upward since it opens upward. {y|y>=-10/3}
\n" ); document.write( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C3x%5E2-8x%2B2%29\"
