Find the domain and range of the relation. {(−8,−4),(15,14),(−2,15),(14,−11),(19,−19)}
slega [8]

Domain = {-8,15,-2,14,19}

Range = {-4,14,15,-11,-19}

Step-by-step explanation:

When a function is given in the form of a relation containing ordered pairs

The first element of each ordered pair is the member of the domain while the second element of each ordered pair is the member of the range.

Given relation is:

{(−8,−4),(15,14),(−2,15),(14,−11),(19,−19)}

We have to combine the first elements of each ordered pair to make the domain set and second element of each ordered pair to make the range set.

So,

Domain = {-8,15,-2,14,19}

Range = {-4,14,15,-11,-19}

Keywords: sets, domain, range

Describe the transformation that occurs when:
arlik [135]

Answer:

The graph is being stretched vertically, so it will be thinner.

Step-by-step explanation:

g(x) = 8f(x) means that you are multiplying each original y-value by 8, so the graph gets thinner. When there's a number n greater than 1 in front of the function, it's a vertical stretch by n.

HELP!!!!!!!!!!!
Svetradugi [14.3K]

Using the mean concept, it is found that:

Relative to Sabrina's goal, her average swim time over the last five weeks is 0.1 hours.

-----------------------

The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.

In this problem:

  • The data-set is her swim time relative to her goal, which is: {1.25, -1, 2.25, 0, -2.}
  • 5 observations.

Thus, the mean is:

M = \frac{1.25 - 1 + 2.25 + 0 - 2}{5} = 0.1

Relative to Sabrina's goal, her average swim time over the last five weeks is 0.1 hours.
