Answer:

g(-4) = -4

g(-2) = 1

g(1) = -4

Step-by-step explanation:

The value of the given function is -4 for all values of x other than -2 and 1 if x=-2

So,

For x=-4 the value of function will be -4.

g(-4) = -4

For x=-2

The value of function is -2.

g(-2) = 1

And for x=1, the value will be -4.

g(1) = -4 ..

What is P(A and B)?
Wittaler [7]

Answer: the fraction 3/7

=====================================================

Explanation:

We have 7 places: India, Tokyo, Houston, Peru, New York, Tijuana, Canada

Out of these 7 places, 3 of them are both a city and in North America. Those three places are: Houston, New York, Tijuana

We divide the two values (smaller over larger) to get the final answer 3/7

writing P(A and B) is shorthand for asking for the probability of getting a city AND that place is also in north america as well.
