The graph shows the temperature of ice cream in an ice chest during an overnight trip. What is the domain of this function?

mariarad [96]

Let

x-------> the number of hours

y------> the temperature in degrees Fahrenheit

we know that

For $x=0\ hours$

$y=-10\°\ F$

For $x=30\ hours$

$y=30\°\ F$

The domain of the function is the interval----------> $[0,30]$

$0\ hours \leq x\leq 30\ hours$

The range of the function is the interval----------> $[-10,30]$

$-10\°\ F \leq y\leq 30\°\ F$

therefore

<u>the answer is</u>

The domain is all real numbers 0 through 30

The cost of having photos taken includes a sitting fee and $12 for each portrait. The cost of 3,6, and 9 photos respectively is

Eddi Din [679]

Answer:The sitting fee is 15 dollars

Step-by-step explanation:If you were to use the formula y=mx+b then the starting equation would be y=12x+b. It already gave you the cost for the amount of photos respectively so 51=12(3)+b. 12 times 3 equals 36 and 51 minus 36 equals 15. The same way would be used for 87 dollars and 123 dollars while using the amount of photos respectively. 87=12(6)+b. 12 times 6 equals 72. 72 plus 15 equals 87. 123=12(9)+b. 12 times 9 equals 108. 108 plus 15 equals 123. Therefore the sitting fee is 15. (51=12(3)+15, 87=12(6)+15, 123=12(9)+15)
