f(x) is relatively large.

Note the difference between the last two estimates, as well as the relatively large value for f(x). The problem is that there is no value of x for which f(x) equals zero. However, at x = 1.99999999999, there is a neighboring value of x that yields ant opposite sign for f(x).

x2 6

As x approaches 6 , f(x) becomes a very large positive or negative number.

Enter the equation as an expression.
