How to find the inverse of a linear equation domain and range

What is the first step in finding the inverse of a function?

• Replace the function notation with 'Y'

• Swap the variables X and Y

• Solve for Y

• Find the domain

Why is it important to swap the variables X and Y when finding an inverse?

• To practice the process

• To find the domain

• To simplify the equation

• To find the range

What are the restrictions to consider when determining the domain of a function?

• The function must be increasing

• You cannot divide by zero or take the square root of a negative number

• The function must be differentiable

• The function must be continuous

How can you eliminate a fraction when solving for the inverse of a function?

• Multiply by the reciprocal

• Divide by the reciprocal

• Add the same number to both sides

• Subtract the same number from both sides

What is the relationship between the range of a function and the domain of its inverse?

• They are the same

• The range of the function is the domain of its inverse

• They are unrelated

• The domain of the function is the range of its inverse
