: Write the equation for a horizontal line. Then explain how the line has no functional inverse.

Solution

equation of horizontal line :

y = k where k is a constant

points on this line are ( 1, k) , (3, k) ,,,,,( 100, k)

You can find the inverse algebraically, by flipping the x- and y-coordinates , but here ther is no x in y =k so, we cannot find the inverse.
