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
