Graph this: \n" ); document.write( " \n" ); document.write( "By inspection, x=-4 is a root with multiplicity 3, and so is x=-0.5. Both of those make the parentheses 0, and they cross the x-axis. \n" ); document.write( "- \n" ); document.write( "Take the derivative of the function: \n" ); document.write( "f'(x)=2(x+0.5)*3(x+4)^2+(x+4)^3(2) \n" ); document.write( "as x approaches -4 from the either side, the derivative is negative, or the slope negative. \n" ); document.write( "As x approaches 0.5 from either side, the slope is positive. \n" ); document.write( "There is one turning point where the derivative is 0. \n" ); document.write( "2(x+0.5)*3(x+4)^2+2(x+4)^3=0 \n" ); document.write( "divide both sides by (x+4)^2 \n" ); document.write( "6x+3+2(x+4)=0 \n" ); document.write( "8x+11=0 \n" ); document.write( "x=-1.375 \n" ); document.write( "y=-31.65 \n" ); document.write( "- \n" ); document.write( "end behavior negative is (-x)^4 positive oo \n" ); document.write( "and for positive is x^4 positive oo \n" ); document.write( " \n" ); document.write( " |
