9
8
7
6
5
4
3
2
-12-11-10 -9 -8 -7 -6 -5 -4 -3 -2 -1
1 2 3 4 5 6 7 8 9 10 11 12
- 2
-9
-10
Can somebody help me with this question ? T. i.a (:

Step-by-step explanation:

Range is all possible y values a function can have. Look at the y axis. So let find the max/ min y value the function can have. The max y value is 1, and the minimum y value is -4. All the x Intervals fall between -4, and 1. Since we have solid dot we include the -4 and 1.

So the notation for this is

or

[-4,1]

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
