The table shows several value of the function f(x)=-x^3+x^2-x+2. Complete the missing values in this table, and then use these values and the intermediate value theorem to determine (an) interval(s) where the function must have a zero.
\n" ); document.write( "HERES THE TABLE:
\n" ); document.write( "x -2 -1 0 1 2
\n" ); document.write( "f(x) 16 _ _ _ -4 \r
\n" ); document.write( "\n" ); document.write( "f(-1)=5
\n" ); document.write( "f(0)=2
\n" ); document.write( "f(1)=1
\n" ); document.write( "Since f(1)is positive
\n" ); document.write( "and f(2)is negative
\n" ); document.write( "the graph must pass through the x-axis.
\n" ); document.write( "There must be a zero between x=1 and x=2
\n" ); document.write( "Cheers,
