<u>Given:</u>
It is given that the value of the graph when the input 7 is
We need to determine the value of x when
<u>Value of x when </u><u>:</u>
The value of x can be determined by using the graph.
From the graph, we need to determine the value of x when other than the value x = 7.
This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.
Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.
Therefore, the input value is x = -8 which makes
Hence, the input value other than 7 for which is x = -8.
