Horizontal line test inverse function

A horizontal line is a straight, flat line that goes from left to right. Given a function (i.e. from the real numbers to the real numbers), we can decide if it is injective by looking at horizontal lines that intersect the function's graph. If any horizontal line intersects the graph in more than one point, the function is not injective. To see this, note that the points of intersection have the same y-value (because they lie on the line ) but different x values, which by definition means the function cann… Web1.4.2 Use the horizontal line test to recognize when a function is one-to-one. 1.4.3 Find the inverse of a given function. 1.4.4 Draw the graph of an inverse function. 1.4.5 Evaluate inverse trigonometric functions. An inverse function reverses the operation done by a particular function.
