The correct answer is 2 1/7
Answer:
(Missing part of the question is attached)

Estimates are too large.
Step-by-step explanation:
Suppose the only information we know about the function is:

where the graph of its derivative is shown in the attachment
<h3>(a)</h3>
If the function
is differentiable at point
, the tangent line to the graph of
at 1 is given by the equation:

So we call the linear function:

We know the
as it is given in the question, and
from the graph attached. Substitute in the equation of
.

<h3>(b)</h3>
At x=1,
is positive but it is decreasing. However. if we draw the tangent lines, we see that the tangent lines are becoming less steeper, so the tangent lines lie above the curve
. Thus, The estimates are too large.
I believe the answer is 47.
