The domain of f o g is all x-values less than or equal to 1/4. So, the correct answer is B. 1.
What is Function ?
Function can be defined in which it relates an input to output.
To determine the domain of f o g, we need to first find the composition of f and g.
f o g(x) = f(g(x))
= √4(1/x - 4) = √(4/x - 16)
The domain of f o g is the set of all x-values for which the expression √(4/x - 16) is defined.
For the expression under the square root to be defined, we need:
4/x - 16 ≥ 0
4/x ≥ 16
x ≤ 4/16
x ≤ 1/4
Therefore, the domain of f o g is all x-values less than or equal to 1/4. So, the correct answer is B. 1.
