Answer:
<h2>The graph in the attachment.</h2><h2>The inverse is not a function.</h2>Step-by-step explanation:
The graph of the function and its inverse are symmetric with respect to the line y = x.
The inverse is not a function because for x = 3 we has two values of y: -3 and -4 (look at the picture).
<em>A function is a relation that associates each element x of a set X to a single element y of another set Y.</em>
Answer:
W = t + 200
Step-by-step explanation:
Number of words typed in the first letter = 200
The relationship between the total words typed, W and the number of seconds, t spent on the second letter :
W = number of words typed in first letter + t
W = 200 + t
Choosing any pair of values from the table :
W = 245 ; t = 45
W = 200 + 45
W = 245
Therefore, the number of words, W typed today can be represented as
W = 200 + t
