Question 1018400
I think they are trying to say that the domain
is is the x-value of only 3 points:
( 1,0 )
( 2,1/2)
( 4, 1 )
--------
The domain is:
D{ 1, 2, 4 }
Since the domain is only 3 values, the the range
can only be 3 values:
R{ 0, 1/2, 1 }
-------------------
Here's the calculations:
-------------------
{{{ f(x) = log( 4,x ) }}}
{{{ f(1) = log( 4,1 ) }}}
{{{ f(1) = 0 }}}
-----------------
{{{ f(2) = log( 4,2 ) }}}
{{{ f(2) = 1/2 }}}
-----------------
{{{ f(4) = log( 4,4 ) }}}
{{{ f(4) = 1 }}}
