Step-by-step explanation:
When given the following functions,
One is asked to find the following,
1. Question 1
When finding the inverse of a function that is composed of defined points, one substitutes the input given into the function, then finds the output. After doing so, one must substitute the output into the function, and find its output. Thus, finding the inverse of the given input;
2. Question 2
Finding the inverse of a continuous function is essentially finding the opposite of the function. An easy trick to do so is to treat the evaluator (h(x)) like another variable. Solve the equation for (x) in terms of (h(x)). Then rewrite the equation in inverse function notation,
3. Question 3
This question essentially asks one to find the composition of the function. In essence, substitute function (h) into function () and simplify. Then substitute (-3) into the result.
Now substitute (-3) in place of (x),

Answer:
71.447296
Step-by-step explanation:
The sequence is geometric with first term 100 and common ratio -0.4. Then the sum of n terms is ...
Sn = 100(1 -(-0.4)^n)/(1 -(-0.4))
and the sum of 9 terms is ...
S9 = 100(1 -(-0.4^9))/(1.4) = 71.447296
