Answer:
-1<x<1 and 1<x
Step-by-step explanation:
We are asked to determine the interval in which our function shown in the graph has positive values.
In order to do so, we have to see for what values of x on x axis, the graph is above x axis.
As we can see in the graph, when we move from x = -1 towards right, the graph is above x axis. And towards left of x=-1 , the graph is below x axis. Hence answer is
-1<x<1 and 1<x
(2x)sqrt 2- 64y2 is the answer
In 7 hours 644 newpapers
in one hour it is 644/7= 92
in 9 hours-> 92x9 =828 newspapers
