WebDec 22, 2015 · Given the graph of f (which is, I think, what you mean by "diagram"), start by marking the given value of x on the y- axis, go horizontally to the graph then then vertically to the x-axis to determine the value of y. The point is that taking the inverse function "swaps" x and y. Share. Cite. Follow answered Dec 22, 2015 at 12:47. user247327 ... WebJan 2, 2024 · HOW TO: Given a function f(x), use a graph to find the limits and a function value as x approaches a. Examine the graph to determine whether a left-hand limit exists. Examine the graph to determine whether a right-hand limit exists. If the two one-sided limits exist and are equal, then there is a two-sided limit—what we normally call a “limit.”
