Answer 1

Answer:

Answer: B

Step-by-step explanation:

To find the inverse function, you switch x with y and y with x. Then, you solve for y.

$y=(x-1)^(2) -4$ [switch x with y, and y with x]

$x=(y-1)^2-4$ [add both sides by 4]

$x+4=(y-1)^2$ [square root both sides]

$√(x+4) =y-1$ [add both sides by 1]

$√(x+4) +1=y$

$f^-^1(x)=1+√(x+4)$

Now that we know the inverse function, we can actually tell that the answer is B. We know this because of the restriction that f(x) is x≤1. This makes it positive, and B the answer.

Answer:

D) {-1}

Step-by-step explanation:

A rational expression is "not defined" when its denominator is zero. Hence to find values of x that make the expression "not defined," you solve the equation ...

denominator = 0

2x +2 = 0 . . . . . . put the actual denominator into the equation

x + 1 = 0 . . . . . divide by 2

x = -1 . . . . . . . . subtract 1

The expression is "not defined" for x in the set {-1}.

Answer:

Scientific notation is a way to make these numbers easier to work with. In scientific notation, you move the decimal place until you have a number between 1 and 10. Then you add a power of ten that tells how many places you moved the decimal.
