Determine which of the following relations is a function. (Lesson 1-7) A.{(–4, 3), (−2, −2), (0, 2), (0, 5)}
B.{(−3, 1), (−3, 3), (−2, −1), (0, 5)}
C.{(−4, −1), (−2, −1), (−1, −1), (3, 3)}
D.{(2, −5), {−1, −1), (0, 4), (2, −3)}

c

Step-by-step explanation:

c is a function because the x variables don't repeat. You can't have the same number in x variable position repeat.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
