My question is dealing with Graphing Quadratic Functions.
\n" ); document.write( "The problem is f(x)=xsquared -5.
\n" ); document.write( "**
\n" ); document.write( "y=x^2-5
\n" ); document.write( "you can look at this equation in different ways but one way is to see this equation as a standard form for a parabola: y=A(x-h)^2+k, with (h,k) being the (x,y) coordinates of the center.
\n" ); document.write( "For given equation: y=x^2-5
\n" ); document.write( "Vertex is at (0,-5)
\n" ); document.write( "To get more points plug in values of x.
\n" ); document.write( "But another way is to find x-intercepts:
\n" ); document.write( "x^2-5=0
\n" ); document.write( "x=±√5≈±2.24
\n" ); document.write( "You now have 3 points with which to plot the graph. \n" ); document.write( "
\n" );
