Explain why a graph that fails the vertical-line test does not represent a function

1 answer:

5 0

For any given y value, there can only be one x value. Let's consider a graph with a line that curves and intersects x=2 twice. This would mean that if you plug 2 into the function you would get two answers. However, this is not possible as plugging in any value to x will result in only one answer. For example, if y= 4x + 3, no matter how many times I plug a number in there, I'm always going to get the same y value, and this is true for all real functions.

If you have 12 customers in a lawn care business, what is the minimum number of times you need to mow per customer each month to

I believe the answer would be D. Because, 10*12= 120 and 400/120= 3.33
Since you are talking about money, you would round up.

Meaning that the answer should be D.

It's like simple math but the sign of the answer would be the opposite.
