Answer:
f(x)^-1=x-2/10
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given
x² - 6x + 9
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the x- term (- 6)
The factors are - 3 and - 3, since
- 3 × - 3 = + 9 and - 3 - 3 = - 6, thus
x² - 6x + 9 = (x - 3)(x - 3) = (x - 3)² → C
10, 5, 20, 10, 40, 20, 80, 40, 160, 80,
Next Three Numbers: 20, 80, 40
Pattern: Take half of the first term. 1/2 of 10 = 5 which is the second term.
Next, multiply the second term by 4. 5 times 4 = 20
Divide 20 by 4 to get 10
Multiply 10 by 4 to get 40
---------------
Take half of 40 to get 20 (the first of the three missing terms)
Multiply 20 by 4 to get 80 (the second missing term)
Multiply 80 by 1/2 to get 40 (the third missing term)
This is a more difficult one to explain. Let's start with the line to the right. It has a slope (m) of 
= -1 and a y-intercept of +3 (continue the line to see where it crosses the y-axis). So, the equation of that line is: y = -x + 3 when x ≥ 2. This can also be written as y = 3 - x when x ≥ 2. The only option that has that equation is A.
Answer: A
Answer should be rational
