Find the Domain A(200)=-2000/((200)^2)

Problem

A(200)=(−2000)/200

Solution

1. Identify the function type. The expression is a rational function of the form ƒ(x)=g(x)/h(x)

2. Determine the condition for the domain. For a rational function, the domain consists of all real numbers except those that make the denominator equal to zero.

3. Set the denominator equal to zero to find the excluded values.

x2=0

4. Solve for x

x=0

5. State the domain. Since the only value that makes the denominator zero is x=0 the domain is all real numbers except 0

Final Answer

Domain={[x∈ℝ,x≠0]}
