Graph this:
\n" ); document.write( "\"graph%28300%2C300%2C-10%2C10%2C-50%2C25%2C2%28x%2B0.5%29%28x%2B4%29%5E3%29\"; \"graph%28300%2C300%2C-5%2C5%2C-5%2C5%2C2%28x%2B0.5%29%28x%2B4%29%5E3%29\"
\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
