Answer: n > 2.5 or n < -2.5
Step-by-step explanation:
Let's solve your inequality step-by-step.
1. Solve Absolute Value.
|n| > 2.5
We know either n > 2.5 or n < -2.5
n > 2.5 (Possibility 1)
n < -2.5 (Possibility 2)
Your answer is n > 2.5 or n < -2.5
Answer:
{(-1,4), (2,7), (3,7)} is a function
Step-by-step explanation:
For something to be a function, any given x must have one and only one y
{(-1,-3), (3,2), (3,7)}
-1(x) only has -3(y)
3(x) has 2(y) and 7(y), making it not a function
{(-3,7), (3,-7), (3,7)}
-3(x) only has 7(y)
3(x) has -7(y) and -7(y, making it not a function
{(-1,4), (-1,7), (3,5)}
3(x) only has 5(y)
-1(x) has 4(y) and 7(y), making it not a function
{(-1,4), (2,7), (3,7)}
-1(x) only has 4(y)
2(x) only has 7(y)
3(x) only has 7(y)
This is a function
