In addition to handwriting this assignment, please complete our 4th WeBWorK assignment. Note that on the Problem 5 of this WeBWorK assignment you need to differentiate the function

We have not yet discussed how to differentiate this function, but you can use our power rule to do it if you rewrite it as

Read section 1.8 carefully (and its examples) to see how to use the tangent line / linear approbation equation

to approximate a desired value of a given function . In problem 5, for example, you are asked to approximate .
