The excluded values of x are 
and 
Explanation:
The given expression is 
The excluded values are the values in the fraction which makes the denominator equal to 0.
Thus, from the definition of excluded values, let us equate the denominator to 0.
Hence, we have,
Adding both sides of the equation by 1, we get,
Taking square root on both sides of the equation, we get,
Simplifying, we get,
Thus, the excluded values of x are and
Answer:
maximum revenue is 25000
Step-by-step explanation:
The revenue function for a bicycle shop is given by R(x)=x⋅p(x)
Given 
Plug in p(x) in R(x)
Now find out the vertex using formula x=-b/2a
a= -0.4, b=200
Plug in 250 for x in R(x)
So maximum revenue is 25000
