we know that
In the graph the intersection both functions is the point when f(x)=g(x)
so
see the graph
the point of intersection both graphs is [tex](1.5,2)[/tex]
that means
for the input value of [tex]x=1.5[/tex]
[tex]f(1.5)=g(1.5)=2[/tex]
therefore
the answer is
the input value is [tex]x=1.5[/tex]
