Question

3 PARTS FOR 40 PIONTS AND BRIANLY, TYSM IF YOU ANSWER WITH LOVE AND CARE.

Answer 1

The domain of the function is [0.70, 2.55]

• The range is [1.04, 2.56]
• The domain is the set of x values and the range is the set of y values

How to determine the domain of the function?

From the question, we have the following parameters that can be used in our computation:

(0.70)(1.04)(1.15)(1.38)(1.86)(1.70)(2.55)(1.29)(2.22)(2.56)

When represented as a table, we have:

x            y

0.70    1.04

1.15      1.38

1.86     1.70

2.55     1.29

2.22    2.56

Remove the y values

So, we have

x = {0.70, 1.15, 1.86, 2.55, 2.22}

As an interval notation, we have: [0.70, 2.55]

This set of values is the domain

How to determine the range of the function?

In (a), we have the following table of values

x            y

0.70    1.04

1.15      1.38

1.86     1.70

2.55     1.29

2.22    2.56

Remove the x values

So, we have

y = {1.04, 1.38, 1.70, 1.29, 2.56}

As an interval notation, we have: [1.04, 2.56]

This set of values is the range

How the domain and the range are calculated

To determine the domain, we make use of the x values

While the y values are used to represent the range
