According to the given plot, . Then the linear approximation to
at
is
Then
On the interval [0, 1], the plot of is positive, so
is an increasing function here. But we can see that
is approaching 0. This means tangent lines to
have a positive slope, but the slopes are approaching 0 and are thus becoming less steep. This in turn means the tangent lines lie above the curve, so the approximations are greater than the actual values of
and
