``y   =   x^3 +   2``

``y   =   ln  (x  −   2)  (where  x   >   2)``

``````Suppose that    f(x)    =   ln  x   for all positive    x   and g(x)    =   9   −   x^2     for all real    x.
The domain  of  f(g(x)) is
{x  |   x   3}
{x  |   |x|     3}
{x  |   |x| >   3}
{x  |   |x| <   3}
{x  |   0   <   x   <   3}
Suppose (as in  Question    29) that    f(x)    =   ln  x   for all positive    x   and g(x)    =   9
−   x^2     for all real    x.  The range   of  y   =   f(g(x)) is
{y  |   y   >   0}
{y  |   0   <   y   ln  9}
{y  |   y   ln  9}
{y  |   y   <   0}
none    of  these``````
