Example:

Definition of Multiplicative Inverse:
For any given nonzero real number x, the reciprocal,

(or multiplicative inverse), of the number is: click refresh (F5)

So, the multiplicative inverse of x = -1.23 can be written as click refresh (F5)...

This problem can be solved using the graphing calculator below by entering -1/1.23 in the Function f(x)= box
Then click on the Plot Graph button. The answer will appear as f(x)= -0.813... below the Function f(x)=box
