Mashcka [7]3 years ago

The second choice is not a relation.

The first and third choices have multiple (input, output) pairs that have the same input. Such a relation is not a function. Any time you see this, you know the relation is NOT a function.

The best answer is the 4th choice ...

... {(0, -9), (-9, 0), (-3, -3)}

Examine the following graph, where P(x) is the preimage and I(x) is the image after a transformation.
Arisa [49]

Answer:

the 4th answer I(x) = P(x-4)

Step-by-step explanation:

the first 2 options are out, because just adding values to the functional result values changes the y value, and the curve is pushed up or down. but not to the side.

just imagine

I(x) = P(x-4) means that the function value of previously at x-4 happens now at x. 4 units "later" (or more to the right).

"x+4" would make the functional value at previously x+4 happen now at x. so, everything would shift to the left (happen "earlier").

therefore, the 4th answer option is correct.

A grid shows the positions of a subway stop and your house. The subway stop is located at (–9, 7) and your house is located at (
miv72 [106K]
For this case, the first thing you should do is use the distance between points formula.
 We have then:
 d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
 Substituting we have:
 d = root ((9 - (- 9)) ^ 2 + (-2-7) ^ 2)
 d = 20.1246118
 Rounding off we have:
 d = 20 units
 Answer:
 
The distance, to the nearest unit, between your house and the subway stop is:
