<h2><u>Answer:</u></h2><h2>y=x^2 has an inverse but it is not a function</h2><h2><u>Step-by-step explanation:</u></h2><h2>y = x</h2><h2>y=x has an inverse function. y=x is the equation of a line. All line has an inverse function and it is also a function</h2><h2>y = 2x + 1 is the equation of a line.</h2><h2>All line has an inverse function and it is also a function</h2><h2>y = x^2 is the equation of a quadratic Quadratic equation has an inverse but it does not pass vertical line test.Hence it is not a function</h2><h2><u></u></h2><h2><u>Thank you</u></h2><h2><u>sunshinemadison101</u></h2>

How to write domain and range

AlekseyPX

Domain is the complete list of x-values that a function can have, and the range is the complete list of y-values that a function can have.

Domain and range can be written as (x, y) if the domain/range does not include the x or y value.

Domain/range can be written as [x, y] if the domain/range does include the x or y value.

If the function has multiple intervals, we use U to symbolize "union."
