When x=-2
f(x) =3(-2) -12 =-6-12=-18
When x=2
f(x) = 3(2)-12=6-12=-6
So For the domain (-2,2)
Range of the function f(x) is (-18,-6)
So (-18 ,-6). is your answer.
Hope it helps....

Answer:
418.88 ~ 419
Step-by-step explanation:
100℅ = 476
12℅. = x
x = 12℅ × 476/100℅
x = 57.12
so the population increased by 57.12 students
476-57.12=418.88
Answer:
1563
Step-by-step explanation:
x= 1 bag of bananas
so, 4x=2084
Divide 2084 by 4 to find how much 1 bag of bananas would cost. 2084/4= 521.
To find how much 3 bags of bananas would cost, multiply 521 (the price of one bag) by 3. 521x3= 1563
3 bags of bananas are $1563
ANSWER
![A=222\operatorname{cm}](https://tex.z-dn.net/?f=A%3D222%5Coperatorname%7Bcm%7D)
EXPLANATION
A) From the diagram, we see that the base of the triangular face is 4 cm long and the height of the triangular face is 3 cm.
B) From the diagram, we see that the length of two of the rectangular face is 15 cm and the width of the rectangular face is 5 cm.
The third rectangular face has a length of 15 cm and a width of 4 cm.
C) The surface area of the prism is the sum of the areas of the faces of the prism.
The area of a triangle is given as:
![A=\frac{1}{2}\cdot b\cdot h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20b%5Ccdot%20h)
where b = base, h = height
The area of a rectangle is given as:
![A=l\cdot w](https://tex.z-dn.net/?f=A%3Dl%5Ccdot%20w)
where l = length, w = width
Therefore, the surface area of the prism is:
Answer:
3
