Chapter 2: Q. 21 (page 69)

Determine whether each relation represents a function. For each function, state the domain and range.

{(1,3),(2,3),(3,3),(4,3)}

Short Answer

Expert verified

The domain of function is{1,2,3,4} and range is{3}.

Step by step solution

01

Step 1. Given Information 

In the given question we have to determine whether each relation represents a function and for each function, we have to state the domain and range.

{(1,3),(2,3),(3,3),(4,3)}

02

Step 2. This relation is a function because there are no ordered pairs with the same first element and different second elements. 

The domain is the set of all the values of x.

Domain:{1,2,3,4}

03

Step 3. The range is the set of all values of y.

Range:{3}

Exploration Graph y=x2. Then on the same screen graph y=-x2. What pattern do you observe? Now try y=x and y=-x. What do you conclude?

A circle of radius ris in inscribed in a square. See the figure.

Part (a): Express the area A of the square as a function of the radius rof the circle.

Part (b): Express the perimeter p of the square as a function of the radius rof the circle.

In Problems 33– 44, determine algebraically whether each function is even, odd, or neither.

g(x)=x2+3x2-1

Graph the function using the techniques of shifting, compressing, stretching, and/or reflecting. Start with the graph of the basic function and show all stages. Be sure to show at least three key points. Find the domain and the range of each function. Verify your results using a graphing utility.

h(x)=x-2

In Problems 7–18, match each graph to one of the following functions:

A.y=x2+2B.y=-x2+2C.y=x+2D.y=-x+2E.y=(x-2)2F.y=-(x+2)2G.y=x-2H.y=-x+2I.y=2x2J.y=-2x2K.y=2xL.y=-2x
