Answer to Problem 1CT
Solution:
The composite function
The domain of
Explanation of Solution
Given information:
The functions
The definition of a composite function is
Plug in
To find
Hence, the composite function is
Now, to find the domain of
The domain of the composite function
First, find the domain of
The function
Polynomial is defined everywhere.
Thus, the domain of the function
Next, find the domain of
The function
The rational function is undefined at the point where the denominator is zero.
Here, the denominator of
Equate denominator
Therefore, the function
That is, in interval notation
Thus, the domain of function
Thus, the domain of
This means that
Now, solve the equation
Subtract
Divide both sides by
Therefore, exclude
Therefore, the domain of the function
Therefore, the domain of the function
(b)
The value of
