Answer:
-♾ < y < 5
Explanation:
Range is set of all possible values for Y.
To know the range of value from graph one needs to see points on axis beyond which the curve does not move.
Alternatively, we can say range is the value of y which is limiting the movement of curve beyond those limits.
Here we can see that upper point on curve is constrained at midpoint of 4 and 6 which is point 5.
Thus, upper limit is 5
which can be written as
y<5
___________________________________
For lower limit , it
Since , the at lower end curve is extended till the end of graph and the end of graph represents infinity. Also, this infinity is on the negative side of y .
Then lower end is -♾ .
which can be written as
y> -♾
Also we can see that graph is continuous one as there is no break in the curve between 5 and -♾.
Thus range of curve is from minus infinity to 5
which can be expressed as
-♾ < y < 5
