Answer:

Not a function.

Does not pass vertical line test.

Step-by-step explanation:

Something called a vertical line test is used to determine if a relation that has been graphed is a function or not.

We say if it passes then it is a function.

It will pass if you are able to draw infinitely many vertical lines covering the whole graph and each vertical line either touches your relation once or none.

If a single vertical line that you draw touches more than once, then it isn't a function.

When I say draw, I don't mean you should physically do it, but more so imagine it.

Now this particular relation is not a function because I can find a vertical line that touches more than once. Take the vertical line x=5 for example.

It will touch at (5,-6) and (5,6). You cannot have an x assigned to more than one y.

Help AB and CD are straight lines find z

chubhunter [2.5K]

Answer: z=16

Step-by-step explanation:

Angles on a straight line add up to 180.

As AB is a straight line we can use that to help us find z.

So you would do 68+85+11=164 (I got the 11 from the angle trapped between like C and F as opposite angles are the same).

Then you would do 180-164=16

So z=16

Hope this helps :)

Find a formula for the described function. A rectangle has perimeter 16 m. Express the area A of the rectangle as a function of

Alex17521 [72]

Part A:

Let the length of one of the sides of the rectangle be L, then the length of the other side is obtained as follow.

Let the length of the other side be x, then

$2(L+x)=16 \\ \\ \Rightarrow L+x=8 \\ \\ \Rightarrow x=8-L$

Thus, if the length of one of the side is x, the length of the other side is 8 - L.

Hence, the area of the rectangle in terms of L is given by

$L(8 - L) = 8L-L^2$

Part B:

To find the domain of A

Recall that the domain of a function is the set of values which can be assumed by the independent variable. In this case, the domain is the set of values that L can take.

Notice that the length of a side of a rectangle cannot be negative or 0, thus L cannot be 8 as 8 - 8 = 0 or any number greater than 8.

Hence the domain of the area are the set of values between 0 and 8 not inclusive.

Therefore,

$dom(Area)=0\ \textless \ L\ \textless \ 8 \ or \ (0, 8)$
