We generalize the Caristi’s fixed point theorem for single valued as well as multivalued mappings defined on a metric space endowed with a graph and w-distance. Particularly, we modify the concept of ...

Note that there are two solutions since the curve and x -axis intersect at two points. Example Using the graph from the previous example to solve the equation 2 x 2 + 2 x 4 = 4.

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to ...
