Answer:

Yes; domain: all real numbers; range: y $\geq$ 0

Step-by-step explanation:

1. Use the vertical line test to see if it is a function.

2. Figure out what the lowest and highest point x can be. In this case x can be any number

3. Figure out what the lowest and highest point of y can be. In this case y is not negative, the lowest it can be is 0. So y $\geq$ 0

*Note: Domain are the x values & Range are the y values

PLEASE GIVE AN EXPLANATION WITH YOUR ANSWER! The table below shows the change in the value of shares over the last three years.

First, lets convert them into multipliers:

The multiplier for a:

25% increase = 1.25

40% decrease = 0.6

40% increase = 1.4

Now to work out the overall percentage change, we just times all of the multipliers together, and convert it back to a percentage:

1.25 x 0.6 x 1.4 = 1.05

So the overall multiplier is 1.05

And a multiplier of 1.05 = a <u>5% increase</u>.

That means that the percentage change is + 5%

Answer:

The percentage change in shares from the start of 2013 to the end of 2015 is:

+ 5%
