<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>
