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!

2x-5/5 +x-2=3(x+5). Find the value of x?
deff fn [24]

Answer:

Step-by-step explanation:

\frac{2x - 5}{5} + x - 2 = 3(x + 5)

\frac{2x - 5}{5} + x - 2 = 3x + 15

\frac{2x - 5}{5} = 2x + 17

2x - 5 = 10x + 85

-8x = 90

x = \frac{-45}{4}
