The graph must be one-to-one and onto. This is verified by the graph of the function passing the vertical and horizontal line test or by looking at the equation. If there is only one variable, then it is imposs

Now that we can find the inverse of a function, we will explore the graphs of functions and their inverses. Let us return to the quadratic function f(x)=x2f(x)=x2 restricted to the domain [0,∞)[0,∞), on which this function is one-to-one, and graph it as in Figu...
The graph of the inverse of a function f(x) can be found as follows: Reflect the graph about the x-axis, then rotate it 90° counterclockwise(If we take the graph on the left to be the right-hand branch of y = x2, then the graph on the right is its inverse, y = .)...
So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the function name, like this:f-1(y)We say "f inverse of y"So, the inverse of f(x) = 2x+3 is written:f-1(y) = (y-3)/2...
f is written as f –1: note that this does not mean ‘1 over f ’. The graph of y = f –1(x) is the reflection in y = x of the graph of y = f (x).例题:To find the inverse of a function x → y (i) interchange x and y(ii) find y in terms of x.小试牛刀:
A function ff is one-to-one if and only if every horizontal line intersects the graph of ff no more than once. Figure 2. (a) The function f(x)=x2f(x)=x2 is not one-to-one because it fails the horizontal line test. (b) The function f(x)=x3f(x)=x3 is one-to-one because...
Graph of Function and Inverse The graph of a function and its inverse is interesting. When you plot the two curves, then draw a line corresponding to the function, y = x, you'll notice that the line appears as a "mirror." Any curve or line below y = x...

designed, is simple in structure and low in cost, can vividly demonstrate the inverse function graph of the function, and can make students understand the graph position relation and the geometric significance of the function and the inverse function thereof in the same plane rectangular coordinate ...
