D. ƒ –1(x) = 25(x – 2)2, x ≥ 0
1 answer:
Answer:

Step-by-step explanation:
The inverse function can be found by solving ...
f(y) = x
(√y)/5 +2 = x
(√y)/5 = x -2 . . . . . subtract 2
√y = 5(x -2) . . . . . . multiply by 5
y = 25(x -2)² . . . . . square both sides
The inverse function is ...

Step-by-step explanation:
Completing the square :
- 9y² - x - 18y + 10 = 0
- 9y² - 18y + 9 - 9 - x + 10 = 0
- <u>(3y - 3)² - x + 1 = 0</u>

The mistake she made was timesing the 6 by the -7.5 as there is no x after the 6
Therefore:
-3.8(-7.5) +6
28.5+6 =34.5
Answer:
3/8
Step-by-step explanation:
75% or 0.75 is equivalent to 3/4
3/4 times 1/2 equals 3/8
