When a problem asks for f(5), what is it asking for? a. the value of f(x) when x = 5 b. the value of x when f(x) = 5 c. the product of f(x) and 5 d. the fifth letter of the alphabet

Here we have this function f(5)

Suppose the original function was f(x).

Now if we have to find the value of the function f(x) when we are given x=5, then we replace the x by 5.

So the function becomes f(5) at x=5.

For example:

If we have a function,

and we are to find value of this function at x=2,

then we replace the x by 2 everywhere in the function,

So this is how it works.

When a problem asks for f(5), it is asking for value of the function f(x) when x=5. Option A. is correct choice.

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.

where did you get them? if you picked from the grass, is is probably poisonous.
