Chapter 1: Problem 9
Find \(f(g(x))\) and \(g(f(x))\) and determine whether each pair of functions \(f\) and \(g\) are inverses of each other. $$f(x)=-x \text { and } g(x)=-x$$

Here is the Federal Tax Rate Schedule \(X\) that specifies the tax owed by a
single taxpayer for a recent year. (TABLE CANNOT COPY)
The preceding tax table can be modeled by a piecewise function, where \(x\)
represents the taxable income of a single taxpayer and \(T(x)\) is the tax owed:
$$T(x)=\left\\{\begin{array}{ccc}
0.10 x & \text { if } & 0
Determine whether the graph of \(x^{2}-y^{3}=2\) is symmetric with respect to the \(y\) -axis, the \(x\) -axis, the origin, more than one of these, or none of these. (Section \(1.3,\) Examples 2 and 3)
Use a graphing utility to graph each function. Use \(a[-5,5,1]\) by [-5,5,1] viewing rectangle. Then find the intervals on which the function is increasing, decreasing, or constant. $$f(x)=x^{3}-6 x^{2}+9 x+1$$
Determine whether each statement makes sense or does not make sense, and explain your reasoning.I used a function to model data from 1990 through 2015 .I have two functions. Function \(f\) models total world population \(x\) years after 2000 and function \(g\) models population of the world's more-developed regions \(x\) years after 2000.1 can use \(f-g\) to determine the population of the world's less-developed regions for the years in both function's domains.
Will help you prepare for the material covered in the next section. Find the perimeter and the area of each rectangle with the given dimensions: a. 40 yards by 30 yards b. 50 yards by 20 yards.
