#### How to determine if a graph is a function
y = 2 x − 3 and its graph as we developed the vertical line test. We said that the relation defined by the equation. y = 2 x − 3. y = 2 x − 3 is a function. We can write this as in function notation as. f ( x) = 2 x − 3. f ( x) = 2 x − 3. It still means the same thing. The graph of the function is the graph of all ordered pairs.Let A = {1, 4, 9, 16} and B = {-1, 2, -3, -4, 5, 6}. Examine whether the relation given below is a function from A to B. In case of a function, write down its range. f = { (1, -1), (4, 2), (9, -3), (16, -4)} Solution : Domain of f = {1, 4, 9, 16} = A. Each element in A has a unique image in B.There are many non-calculus techniques that can be applied to show a function is increasing. One approach is to show for k > 0 that f ( x + k) is larger than f ( x). Here’s a simple example. Suppose that f ( x) = m x + b Now take k > 0 and compare f ( x) to f ( x + k). f ( x + k) − f ( x) = m k. Since k > 0 we know that m k is positive iff ... To locate the local maxima and minima from a graph, we need to observe the graph to determine where the graph attains its highest and lowest points, respectively, within an open interval. Like the summit of a roller coaster, the graph of a function is higher at a local maximum than at nearby points on both sides. The Lesson. A function and its inverse function can be plotted on a graph. If the function is plotted as y = f (x), we can reflect it in the line y = x to plot the inverse function y = f−1(x).
