Chapter 2: Q. 25 (page 69)

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

{(-2,4),(-1,1),(0,0),(1,1)}

Short Answer

Expert verified

The domain of function is{-2,-1,0,1} and range is{0,1,4}

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.

{(-2,4),(-1,1),(0,0),(1,1)}

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:{-2,-1,0,1}

03

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

Range:{0,1,4}

A rectangle is inscribed in a circle of radius of 2. See the figure. Let P=x,ybe the point in quadrant I that is a vertex of the rectangle and is on the circle.

Part (a): Express the area Aof the rectangle as a function of x.

Part (b): Express the perimeter pof the rectangle as a function of x.

Part (c): Graph A=Ax. For what value of xis Alargest?

Part (d): Graph p=px. For what value ofxis p largest?

True or FalseThe cube root function is odd and is decreasing on the interval (-鈭�,鈭�).

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.
