Let f(x) = 3x - 6 and g(x) = x - 2. Find g/f and its domain.
Solution:
Given, f(x) = 3x - 6
g(x) = x - 2
We have to find g/f and its domain.
(g/f)(x) = (x - 2)/(3x - 6)
= (x - 2)/3(x - 2)
= 1/3
To find domain,
When x = 2,
(g/f)(2) = (2 - 2)/3(2 - 2) = 0
The function becomes undefined when x = 2.
Therefore, the domain is the set of all real numbers except 2.
Therefore, (g/f)(x) is 1/3 and its domain is the set of all real numbers except 2.
Let f(x) = 3x - 6 and g(x) = x - 2. Find g/f and its domain.
Summary:
Let f(x) = 3x - 6 and g(x) = x - 2, then g/f is 1/3 and its domain is the set of all real numbers except 2.
