Which statement best describes the function below?
f(x)=x2-x2-9x+9

B. It is a many-to-one function.

Step-by-step explanation:

To find what the function below is, you can use the Function Grapher and Calculator from Math is Fun to graph the function.

As you can see, the graph passes the vertical line test, since each x-value has exactly one y-value.

According to the diagram below, the function will be a many-to-one function, since there are y-values that have three different x-values.

So, your answer will be B. it is a many-to-one function.

Hope this helps!

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

answer: check all that apply, where the options?
