I would say so, yes this relation is a function because if graphed it passes the vertical line test.
Check the picture below. Bearing in mind that x = -2 is a vertical line.
Answer:
All angles in a triangle sum up to 180 degrees.
So, 63+71+x=180 degrees.
You add like terms: 134, and then add x.
134+x=180 degrees.
Minus x from both sides.
180-134=x.
What do you think x is?
Answer:
2n + n² -1
Step-by-step explanation:
2n + 2 + n² - 3
2n + n² -1
Lemme know if I read the equation wrong :)
