Chain rule on three functions

The  exercise appears under the Differential calculus Math Mission. This exercise involves finding the value of a number in the function.

Types of Problems
There are three types of problems in this exercise:
 * 1) What is the value of a number in the series?: This problem provides two functions with the graphs shown below. The student is asked to find out what the value of a number in the series is.Chainrule.png
 * 2) What is the rule for the sequence?: This problem gives a function and then asks what the rule is. The student is required to find out the rule and write it below.Rule.png
 * 3) What is the value for a number in the function?: This problem gives a function. Then it asks for the value of a number in the function. The student is required to answer this and write it in the space below. Value.png

Strategies

 * 1) It is important to know which part of the function is the outer function and inner function, so it can be solved easier.

Real-life Applications

 * 1) Functions are everywhere. They come into banking, surveying, flight, teaching, carpentry and automobile distance/mileage calculations.
 * 2) Computer code is entirely function-based.
