Answer:

The correct answer is (D)

Step-by-step explanation:

Given the events X and Y:

X = the price of stock X has increased

Y = the price of stock Y has increased

That means that the complement of these events are:

X' = the price of stock X has not increased

Y' = the price of stock Y has not increased

Hence, the event "the price of stock X has increased and the price of stock Y has not increased" may be written as:

X ∩ Y′

Let f(x) = x2 − 16. find f−1(x). open study

Bogdan [553]

Okay, so first you make f(x) = y and switch x and y. So the equation becomes:

x = y^2 - 16

The next step is to get y by itself. So first you add 16 to both sides:

x + 16 = y^2

Now you square root everything, so the final answer is going to be:

the square root of x + 4 = y
