+<p>
+It should be more clearly stated, but it asks us to find the \(x\). To find the
+intersection point, we first find \(u\) such that \(f(u)=g(u)\).
+\[u^2-2=(u-5)^2+3\Rightarrow u^2-2=u^2-10u+25+3\Rightarrow10u=30\Rightarrow
+u=3\] Then we can evaluate \(f(3)=g(3)=7\) so the intersection point is
+\((3,7)\) so the answer would be 7.
