Graph the given functions. $$v=\sqrt{16-h^{2}}$$

Use a graphing calculator to find the range of the given functions. Use the maximum or minimum feature when needed. $$y=\frac{x^{2}}{x+1}$$

Answer the given questions. The points \((3,-1),(3,0),\) and \((x, y)\) are on the same straight line. Describe this line.

Determine the appropriate functions. A satellite telephone is leased at a cost \(C\) of \(\$ 200\) plus \(\$ 10\) per minute \(t\) the phone is used. For \(t=f(C),\) find \(f(500)\)

Graph the given functions. $$y=\sqrt{x^{2}-16}$$

Use a graphing calculator to find the range of the given functions. Use the maximum or minimum feature when needed. $$y=\frac{x}{x^{2}-4}$$

Answer the given questions. On a circular machine part, holes are to be drilled at the points \((2,2),(-2,2),(-2,-2),\) and \((2,-2),\) where (0,0) represents the center. Plot these points and find the distance between the points in quadrants I and III.

Use a graphing calculator to find the range of the given functions. Use the maximum or minimum feature when needed. $$Y(y)=\frac{y+1}{\sqrt{y-2}}$$

Answer the given questions. Join the points \((-1,-2),(4,-2),(7,2),(2,2)\) and \((-1,-2)\) in order with straight-line segments. Find the distances between successive points and then identify the geometric figure formed.

Use a graphing calculator to find the range of the given functions. Use the maximum or minimum feature when needed. $$f(n)=\frac{n^{2}}{6-2 n}$$
