Definition of
Multiplicative Inverse (reciprocal):
For any given nonzero real number x, the
reciprocal,
(or multiplicative inverse), of the number is:
=\frac{1}{x} )
So, the multiplicative inverse of x = -1.23 can be written as
=\frac{1}{-1.23}=-0.813 )
...
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
Definition of
Additive Inverse (opposite):
For any given nonzero real number x, the
Additive Inverse (opposite),
of the number is:
=-x )
So, the additive inverse (opposite) of x = -1.23 can be written as
=-(-1.23)=1.23 )
...
This problem can be solved using the graphing calculator below by entering -(-1.23) in the Function f(x)= box
Then click on the Plot Graph button. The answer will appear as f(x)= 1.23 below the Function f(x)=box
