9. D because it fits the description when it is graphed. 
11. D because it has the correct vertex, which is (1.5, 4.75). 
12. f(x)=-4(x-2)²+16 works with the table and provided graph!
13. 0 isn't a zero for f(x), so B is correct (the zeros are 1/2 and 4). 
14. The width is about 3.831. 
15. The answer is B because the equation for a parabola in this form is: 
      f(x) = (x - r₁)(x - r₂)

Every one of these except for 15 was solved using desmos, a graphing calculator. 

Hope this helps!

What is the area of the shaded region?<br> DO NOT include the unit of measure in your answer
Aleks04 [339]
The area is 73. You have to find the area of both triangles using the formula a = 1/2bh. The shaded triangle is 108 square yards but because another triangle is cut out of it, we need to subtract the area of the white triangle from the shaded triangle. The area of the white triangle is 35. So now we have 108-35 =73. That’s how i got 73.

Select all the equations that are true when x = 4
V125BC [204]

Answer:

B and E

Step-by-step explanation:

A. 8x = 2

8(4) = 2

32 = 2

B. 19 + x = 23

19 + 4 = 23

23 = 23

C. 40/x = 5

40/4 = 5

10 = 5

D. -3x = 12

-3(4) = 12

-12 = 12

E. x - x - x - x = -8

4 - 4 - 4 - 4 = -8

0 - 4 - 4 = -8

-4 - 4 = -8

-4 + (-4) = -8

-8 = -8

makkiz [27]
The domain is the set { -2, 0, 2, 3}
discussion:
the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives -2, 0, 2, 3.
