I'm honestly not really sure, but it has to be either (2,10) or (10,2). I've never seen a question like this...

Answer: NO
<u>Step-by-step explanation:</u>
In order for the function to be one-to-one, it must pass the vertical line test AND the horizontal line test.
The vertical line test is where you draw a vertical line anywhere and the line will not intersect the graph more than one time. In other words, the function cannot contain a duplicate x-value.
The horizontal line test is where you draw a horizontal line anywhere and the line will not intersect the graph more than one time. In other words, the function cannot contain a duplicate y-value.
The graph provided passes the vertical line test but fails the horizontal line test. <em>One example is that there are two x-intercepts.</em>
It depends. Generally no.
Linear equations are generally in the form [math]y=mx+b[/math] and have a domain of [math](-\infty,\infty)[/math], or all real numbers. However, an arithmetic sequence is only defines for the natural numbers (that is, while numbers [math]> 0[/math].
For any two terms in the arithmetic sequence, [math]a_n[/math] and [math]a_{n+1}[/math], there will always be a point on the linear function that lies in between them, and is such not defined in the sequence.
This does not make the sequence and function unrelated, but rather it makes them not the same.
A similar argument applies for geometric sequences and exponential equations.
Answer:
Mary is 
times heavier than her sister
Step-by-step explanation:
Mary's Weight = n
Sister's Weight = n - 15
To find how many times mary is heavier, we need to multiply "that many time" [let it be x] with sister's weight to get Mary's weight.
<u>e.g. </u>If someone weighs 100 and another person 50, 50 * 2 = 100, thus, 100 kg person is 2 times heaving. We do same for this:
(n - 15) * x = n
x = n/(n - 15)
