In order to determine assume and from that point on the -axis, go up vertically until you reach the graph. When you intersect the graph, take note of the corresponding -value on the -axis.
From the graph, we see that
We'll determine in the same way. Start from on the -axis, go vertically up to the graph and take note of the intersection point's -value.
In this case, we need to determine the -value that satisfies the equation Therefore, start at on the graph and identify the corresponding -value.
We see that has to be between and for the expression the be equal to The arrow seems to point a little over the middle, which can be read as a value between , and for instance,
