Using graphing technology graph x^4-7x^3+12x^2+4x-12. Identify for which values of x the graph is increasing.
\n" ); document.write( "-----
\n" ); document.write( "f'(x) = 4x^3 -21x^2 + 24x + 4
\n" ); document.write( "Solve:: 4x^3-21x^2 + 24x+4 > 0
\n" ); document.write( " $\"graph%28400%2C400%2C-10%2C10%2C-10%2C10%2Cx%5E4-7x%5E3%2B12x%5E2%2B4x-12%29\"$
\n" ); document.write( "Ans: increasing from x = 0.1472 to x = 2 and also when x > 3.5
