whats the axis of symmetry, the x-intecept, the y-intercept, the vertex, the range,and the domain for: f(x)= -x^2-10x-26
\n" ); document.write( "**
\n" ); document.write( "f(x)= -x^2-10x-26
\n" ); document.write( "complete the square
\n" ); document.write( "f(x)= -(x^2+10x+25)+25-26
\n" ); document.write( "f(x)=-(x+5)^2-1
\n" ); document.write( "This is an equation of a parabola that opens downwards with vertex at (-5,-1)
\n" ); document.write( "axis of symmetry: x=-5
\n" ); document.write( "..
\n" ); document.write( "y-intercept
\n" ); document.write( "set x=0
\n" ); document.write( "y=-26
\n" ); document.write( "..
\n" ); document.write( "x-intercept
\n" ); document.write( "set y=0
\n" ); document.write( "-(x+5)^2-1=0
\n" ); document.write( "(x+5)^2=-1
\n" ); document.write( "x+5=±√-1
\n" ); document.write( "x=-5±√-1
\n" ); document.write( "no real roots
\n" ); document.write( "x-intercept:none
\n" ); document.write( "..

\n" ); document.write( "Domain: (-∞,∞)
