Carol’s present age = y years
Her daughter’s present age = 25 years

After 6 years
Carols age =y+6
her daughters age=y-25+6=y-31

According to the condition
y+6+y-31
2y-13 = 75
Transporting -13
2y=75+13
2y=88
y=88/2
y=44

Find the least common multiple of x2 – 8x + 12 and x2 – x – 2.
abruzzese [7]
<span>The least common multiple of x² – 8x + 12 and x² – x – 2.

by factoring:
∴ </span><span>x² – 8x + 12 = (x-2)(x-6)

       </span><span>x² – x – 2 = (x-2)(x+1)

note: the factor (x-2) is common between them take it one time

∴ LCM = (x-2)(x-6)(x+1)

Answer:

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}

The relation is a function.

Step-by-step explanation:

A <u>relation</u> is any set of ordered pairs, which can be thought of as (input, output).

A function is a <em>relation</em> in which no two ordered pairs have the same first component and different second components.

Remember that a function can only take on <u>one output for each input</u>. We cannot plug in a value and get out two values.

The Vertical Line Test allows us to know whether or not a graph is actually a function.  If a vertical line intersects the graph in all places <u><em>at exactly one point</em></u>, then the relation is a function.

I did the Vertical Line Test on your given graph. As you can see from the attached screenshot, each vertical line crosses the graph only once. Therefore, the given relation is a function.

The <u><em>domain</em></u> of the given relation is the set of x-values, while the <em><u>range</u></em> is the set of y-values. You'll have to list the ordered pairs in order to determine the domain and range of the given relation.

Relation:  {(-4, -1), (-2, 1), (1, -2), (2, 4), (4, -4)}.

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}
