B is the irrational. C & D are rational as they can be written in a ratio, aka a simple fraction. A is rational as it simplifies to +/-2, a whole number.

The graph of a function is shown:
ziro4ka [17]

Answer:

D) {-2, 1, 2, 5}

Step-by-step explanation:

The "output" of a function will never be an ordered pair, so we can immediately eliminate options A and B.

In this case, the output refers to the y-values of the function.  

Since the ordered pairs are: (-2, 5), (-1, 1), (2, -2), and (5, 2), we see that the output of this function is: 5, 1, -2, 2.

Thus, choice D is correct.

Let me know if this helps!

12345 [234]

Answer: 5

Step-by-step explanation:

a^2 + b^2 = c^2

12^2 + x^2 = 13^2

144 + x^2 = 169

x^2 = 25

square root both sides

x = 5

to check, do 12^2 + 5^2 =169

sqrt of 169 is 13

hope this helps

Which of these is the statement of zero product rule?
Jobisdone [24]
Well there are no statements but the zero power law works like this :
ANYTHING raised to the zero power is 1
that is anything BUT zero itself because 0 to the power of 0vis still 0 and it makes no sense to write 0 to the power of zero.
