Use graphing technology to find the range of the function f(x)=x2 +6x+9

Mathematics
1 answer:
lbvjy [14]3 years ago
5 0

Answer:

See below.

Step-by-step explanation:

Refer to the graph.

The range of a graph is the span of y-values it covers.

From the graph, we can see that the span of y-values is all values greater than or equal to 0.

Therefore, our range is, in interval notation:

[0,\infty)

Note that we use brackets with the 0 because 0 is included in our range.

In set notation, this is:

\{y|y\in\mathbb{R},y\geq 0\}

Alexxx [7]

The value of the car is January 2003 is  $199,148.54.

<h3>What is the value of the car?</h3>

Depreciation is the rate of decline in the value of an asset with the passage of time.

The exponential equation that can be used to determine the value of the car is:

Value of the car = purchase value(1 - rate of decline)^time

400,000 x (1 - 0.16)^(2003 - 1999)

400,000 x (0.84^4) = $199,148.54

Jack has 120 songs on his music player. Some are rock, some are jazz, and the rest of classical pieces. If his music player is o
muminat
2/5 and 1/3 have a common denominator of 15. 6/15, 5/15, and 4/15 add up to 15/15. So the chances of rock are 4/15. 120 divided by 15 is 8. Six times eight equals fourty eight, five times eight equals forty, and four times eight equals thirty two. So there are 48 classical songs, 40 jazz songs, and 32 rock songs.
