Unformatted text preview: (c) Sketch a graph of the function and its inverse. (d) Determine if the inverse is a function. If it is not a f n , restrict the domain of the original f n to its principal branch , so that the inverse is a f n . Example 1 (i) y = x 2 +4x +5 (ii) y = √ x1 (iii) x = y 2 + 1 1.5__The_Inverse_Function.notebook 2 September 11, 2009 Example 2 The area of a corn field (with a 400m perimeter)can be written as a function of its width using the following formula: A(w) = w ( 200 - w) a) Determine the inverse of this area function. b) What does the inverse represent? c) Find the width of the field if the area is 8700m 2 .
