f (x)
The SOLVE operation returns a math error if an estimate produces an operation
that is not allowed — for example, division by zero, a square root of a negative
number, or a logarithm of zero. Keep in mind that SOLVE can generate estimates
over a wide range. You can sometimes avoid math errors by using good guesses.
If a math error occurs, press
see the value that produced the error.
Example:
A Relative Minimum.
Calculate the root of this parabolic equation:
It has a minimum at x = 3.
Enter the equation as an expression:
