Answer: Your answer is correct.
Explanation:
Use the marker gradations to identify the projected geometric shapes from the top, front and right side view as shown in the figure below.
All the gradation markings agree with your choice.

The first limit is known as a left-hand limit. We're approaching x = 3 from the left. This means we start with values smaller than x = 3, say x = 2.5 and move closer to x = 3.
Because x is starting off smaller than 3, we use the first piece of the piecewise function. This is the piece that corresponds to x < 3. So we plug x = 3 into that piece to get
2x^2 - x = 2(3)^2 - 3 = 2(9) - 3 = 18 - 3 = 15
So the result for the left-hand limit is 15.
----------------------------------------------------------
The right hand limit will have us start on the other side of x = 3. We start at x = 3.5 and move closer to x = 3. So we'll use the
portion.
Plug x = 3 into the second piece to get
3 - x = 3 - 3 = 0
--------------------------------------------------------------------------
The result of the left-hand limit was 15
The result of the right-hand limit was 0
The fact that the results do not match up means that the overall limit at x = 3 does NOT exist.
1300 monthly= 15600 annually
1000 biweekly= 24000 annually
550 weekly= 26400 annually
800 semimonthly= 19200 annually
btw annually means yearly
For the 18 oz you pay $1.69 per oz and for 21 oz you pay $1.64 per oz so 21 oz for 12.81 is technically the better buy but the difference in price per ounce is so small that you should buy the size that suits your needs better.
Part A: W=6x
Part B: S=6(40)+9y
Part C: 330=6(40)+9y... 6(40)=240... 330-240=90...
9y=90... 9y/9= y... 90/9=10, therefore y=10
