Answer:
The first one is a function. The other two are not functions.
Step-by-step explanation:
To find this, you use the vertical line test. If the vertical line touches multiple points on the graphed line, it is not a function. If the vertical line only touches the graphed line at one point, it is a function.
Good Luck! I hope this helps!
A / b = -2
Take note:
to have a quotient with at negative sign, both a & b must have opposites signs. a can be a positive number while b is a negative number or vice versa. If both a and b have the same sign, its quotient will be a positive number.
Let us disregard the sign.
To arrive at the answer of 2, a must be twice the amount of b. meaning a = 2b.
For example: look for a if b is equal to 2. a = 2(2) ; a = 4.
a / b = 2
4 / 2 = 2
2 = 2
Now, we consider the sign of both numbers. a can be 4 while b can be -2 OR vice versa.
a / b = -2
4 / -2 = -2 or -4 / 2 = -2
