Answer:
C
Step-by-step explanation:
Each input value can have only one output value for it to be a function. In other words, there should only be one y value for each x value. The only option that satisfies this is C.
Answer:
D. (2, 6)
Step-by-step explanation:
Look at the picture.
Check:
(2, 6) → x = 2, y = 6
Put the coordinates of the point to the inequalities:
y < x² + 6
6 < 2² + 6
6 < 4 + 6
6 < 10 TRUE
y > x² - 4
6 > 2² - 4
6 > 4 - 4
6 > 0 TRUE
18/45 can be divided by nine, so it would be 2/5
