Question

I need it by tmr ill give brainliest thx

Answer 1

Answer:

3. To tell if something is a function, you have to look at its x values. If the x values are repeating it is not a function. It is okay for the y values to be. Y is the function.

4. x is a function

5. Same thing as 3. So it cant be a or b or c but it is D!

6. function only

Step-by-step explanation:

Answer 2

Answer:

3: B

4: D

5: D

6: B

Step-by-step explanation:

3: A function has only one y value per x value, so it can't be W, X, or Z, it has to be Y which is B

4: Vertical line test ensures that every x value only has up to 1 y value.

In W, a vertical line intersects that circle twice

In X, a vertical line intersects the wave infinite times

In Z, a vertical line intersects the sideways parabola twice

In Y, there is an asymptote but at every point a vertical line only intersects once, so the answer is D

5:

Not A because there are 2 y values for 0

Not B because there are 2 y values for both 2 and 3

Not C because there are 2 y values for both 2 and 3

There is no problem in D

6:

This is obviously a relation so it has to be either (a relation) or (a relation and a function)

We can see that every x-value has a single y-value so it has to be a function

It is both a relation and a function
