Use the intermediate value theorem to determine whether the polynomial function has a zero in the given interval.
\n" ); document.write( "f(x) = 8x^3 - 10x^2 + 3x + 5; [-1, 0]
\n" ); document.write( "-------
\n" ); document.write( "f(-1) = 8*-1 - 10*1 + 3*-1 + 5
\n" ); document.write( "f(-1) = -8 -10 -3 + 5 < 0
\n" ); document.write( "------
\n" ); document.write( "f(0) = 5
\n" ); document.write( "---
\n" ); document.write( "Since f(-1) is negative
\n" ); document.write( "And f(0) is positive
\n" ); document.write( "and
\n" ); document.write( "Since f is continuous on [-1,5] there must be a zero on that interval.
