Transcribed Image Text:### Exercise 3: Linear Approximation
In this problem, you will use a linear approximation to determine the value of \((1.1)^{4/3}\).
#### (a) Function and Value of \(x\)
**Question:** What function do you want to approximate here, and at what value of \(x\)?
- \(f(x) =\)
- at \(x =\)
#### (b) Anchor Point
**Question:** What’s a number close to \(x\) where you know the value of this function? This number should be your “anchor point” \(a\).
#### (c) Tangent Line Equation
**Question:** Find the equation of the tangent line to \(f(x)\) at \(x = a\).
#### (d) Approximate Value
**Task:** Plug the value of \(x\) from part (a) into your equation for the tangent line. This is the approximate value of \((1.1)^{4/3}\).
#### (e) Calculate Error and Percent Error
**Task:** All of the above could (in theory) be done without a calculator. Now use a calculator to compute the actual value of \((1.1)^{4/3}\). What is the error? What is the percent error?
