Question
Given the function: \( f(x) = \sqrt[3]{-18x^3} + 45 \), find the equation of the tangent line, or linear approximation, to the graph of the function at \( x = 1 \).

\[ L(x) = \]

Use the tangent line to approximate \( f(1.1) \).

\[ L(1.1) = \]

Compute the actual value of \( f(1.1) \). What is the error between the function value and the linear approximation?

Answer as a positive value only, and round to 5 decimal places.

\[ | \text{error} | \approx \]
