Answer:
f(x) = -2x² + 2
Step-by-step explanation:
If you remember the y = x² parent graph, you will be able to derive your equation from visualization.
The vertex of this graph would be at (0, 2), so your degree coefficient would be negative. Your y-intercept would also be at (0, 2). Since both 1 and -1 are included, you can tell it is a parabola, and hence the 3rd option is your answer.

1. One eighth as a percent is 12.5 %
2. 0.063 as a percent is 6.3%
3. 34.71% live with their parents
4. 23.44% as a decimal is 0.2344
5. Each person should contribute $5
6. The proportion would be 47.57
7. 41 is 84 percent of 205
8. There are 16 students in the entire class.
9a) She took 75 shots.
9b) 24 shots, so thats 15%
10. That's 60 percent.
11. Thats $81.85
For most of these if you want the percentage just divide the number you are given into the total, then you will get a decimal, with that decimal multiply it by 100 and you will get the percent!
'Complement' = difference between an angle an 90 degrees.
'Supplement' = difference between an angle and 180 degrees.
Complement of A = 90 - A
Supplement of A = 180 - A
The problem says that the complement is 1/6 of the supplement, right ?
So <u> 90 - A = (1/6) x (180 - A)</u>
Multiply each side of this equation by 6 :
540 - 6 A = 180 - A
Subtract 180 from each side:
360 - 6 A = - A
Add 6A to each side :
360 = 5 A
Divide each side by 5 :
<u>A = 72°</u>
