Answer:
Function
Step-by-step explanation:
Two different X's could equal the same Y value so this is a function. Remember if there's multiple of the same input (x) equalling different outputs (y) then it is not a function. If there's multiple inputs (x) equalling the same output (y) it's just coincidence and works.
Answer:
Think its 3 but don't enter it, wait for someone else
4x - 24 = -2x + 30
4x + 2x = 30 + 24
6x = 54
x = 9
answer: the number is 9
Answer:
Option b
Step-by-step explanation:
A function is even if and only if f(-x) = f(x).
This means that there is the same value of y for
and for ![-x_0](https://tex.z-dn.net/?f=-x_0)
Where
is any point belonging to the function .
Therefore you must select a graph whose ordered pairs are of the form
and ![(-x_0, y_0)](https://tex.z-dn.net/?f=%28-x_0%2C%20y_0%29)
Therefore the correct answer is option b. Assume that each box in the graph equals 1 unit. Then, for x = 2 y = -3 and for x = -2 y = -3. Then it is shown that the function is even.
