In order to determine $g(100),$ assume $x=100,$ and from that point on the $x$-axis, go up vertically until you reach the graph. When you intersect the graph, take note of the corresponding $y$-value on the $y$-axis.

From the graph, we see that $g(100)=2.$

We'll determine $g(250)$ in the same way. Start from $x=250$ on the $x$-axis, go vertically up to the graph and take note of the intersection point's $y$-value.

Thus, $g(250)≈2.4.$

c

In this case, we need to determine the $x$-value that satisfies the equation $g(x)=1.8.$ Therefore, start at $y=1.8$ on the graph and identify the corresponding $x$-value.

We see that $x$ has to be between $50$ and $75$ for the expression the be equal to $1.8.$ The arrow seems to point a little over the middle, which can be read as a value between $60$, and $65,$ for instance, $x=63.$
