Answer:whats the question asking for?
Step-by-step explanation:
Answer:
y=4
Step-by-step explanation:
The question is asking what is the value of y:
Since all lengths have a dash on them they are all equal :
So 3y = y+8
3y = y + 8
First we subtract y from both sides:
3y-y = y+8-y
2y = 8
Divide both sides by 2:
2y÷2 = 8÷2
y = 4
To check if an expression is indeed a function, you'd use the vertical line test, if it passes, then it IS a function.
now, if it passes the horizontal line test, doesn't mean much function wise, what the dickens is up with the horizontal line test anyway?
well, if the graph, does indeed pass the vertical line test first, is a function, IF then it also passes the horizontal line test, it means, is not only a function but a one-to-one function, meaning there's a unique x-coordinate value for every unique y-coordinate value.
note:
only one-to-one functions have an inverse expression that is also a function.
