document.write( "Question 854379: Analyze the polynomial function f(x)=x^3+x^2-2x Determine the end behavior of the graph of the function. Determine the real zeros of the function and their multiplicity. Use this information to determine whether the graph crosses or touches the x-axis at each x-intercept. Also, determine the domain and range of function as well as the x and y intercepts. Help!! Not sure on any of this!! \n" ); document.write( "

there are three roots
\n" ); document.write( "complex roots always come in pairs
\n" ); document.write( "There are 2 or no complex roots
\n" ); document.write( "There is 1 or three real roots
\n" ); document.write( "three real roots
\n" ); document.write( "0 = x (x^2+x-2)
\n" ); document.write( "0 = (x-1) x (x+2)
\n" ); document.write( "0,1,-2
\n" ); document.write( "the domain and range are the possible values for x and y
\n" ); document.write( "is there any reason to eliminate any numbers?
\n" ); document.write( "division by zero?
\n" ); document.write( "no all real numbers are the range and the domain as well
\n" ); document.write( "
\n" ); document.write( "To find the x intercept set y=0 (find the roots or zeroes)
\n" ); document.write( "To find the y intercepts set x=0
\n" ); document.write( "when x=0 y=0\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
