### Problem 4: Understanding Natural Logarithms with Taylor Polynomials

This problem considers the natural logarithm function \( y = \ln x \).

#### (a) Find Approximations
Find approximations to \( \ln(1.1) \) and \( \ln(0.9) \) using a first-degree Taylor Polynomial.

#### (b) Evaluate Approximations
Use a calculator to decide if these approximations are too high or too low.

#### (c) Graphing and Analysis
Sketch the graph of \( y = \ln x \) and the tangent line at \( x = 1 \). Can you explain your answer to the previous part based on your picture?
