Write each relation as a set of ordered pairs. $$ \begin{array}{|c|c|} \hline \text { Year } & \begin{array}{c} \text { Average Movie } \\ \text { Ticket Price } \\ \text { (in dollars) } \end{array} \\ \hline 1960 & 0.76 \\ 1980 & 2.69 \\ 2000 & 5.39 \\ 2016 & 8.65 \\ \hline \end{array} $$

Write each relation as a set of ordered pairs. $$ \begin{array}{|c|c|} \hline \text { Year } & \begin{array}{c} \text { Average ACT } \\ \text { Composite } \\ \text { Score } \end{array} \\ 2010 & 21.0 \\ 2012 & 21.1 \\ 2014 & 21.0 \\ 2016 & 20.8 \\ \hline \end{array} $$

Let \(f(x)=-3 x+4\) and \(g(x)=-x^{2}+4 x+1 .\) Find the following $$ g(-1) $$

Let \(f(x)=-3 x+4\) and \(g(x)=-x^{2}+4 x+1 .\) Find the following $$ g(3) $$

Use the given information to determine the quadrants in which the point \((x, y)\) must lie. (Hint: Consider the signs of the coordinates in each quadrant, and the signs of their product and quotient.) (a) \(x y>0\) (b) \(x y<0\) (c) \(\frac{1}{y}<0\) (d) \(\frac{1}{y}>0\)

What must be true about the value of at least one of the coordinates of any point that lies along an axis?

Let \(f(x)=-3 x+4\) and \(g(x)=-x^{2}+4 x+1 .\) Find the following $$ g(10) $$

A student plotted the point with coordinates (-4,2) incorrectly by moving 2 units from 0 to the right along the \(x\) -axis and then 4 units down parallel to the \(y\) -axis.

Express each relation using a different form. (For example, if the given form is a set of ordered pairs, use a graph.) There is more than one correct way to do this. \(\\{(0,2),(2,4),(4,6)\\}\)

Let \(f(x)=-3 x+4\) and \(g(x)=-x^{2}+4 x+1 .\) Find the following $$ f(100) $$
