Answer
$\text{a) }
h(250)\approx4
\\\text{b) }
x\approx25$
Work Step by Step
$\bf{\text{Solution Outline:}}$
Use the information in the given graph.
$\bf{\text{Solution Details:}}$
To estimate $
h(250)
,$ find the value of $y$ when $x=
250
.$ Based on the graph, then $
h(250)\approx4
.$
To estimate $
h(x)=2
,$ find the value of $x$ when $y=
2
.$ Based on the graph, $
x\approx25
.$
The answers are
\begin{array}{l}\require{cancel}
\text{a) }
h(250)\approx4
\\\text{b) }
x\approx25
.\end{array}
