A lot of countable nouns or uncountable nouns

A lot of countable nouns or uncountable nouns

A lot of / lots of
You can add plural or uncountable nouns after them
For example: I have lots of / a lot of apples
i have lots of / a lot of water .
English the + last name plural
Does this expression mean "family" or "couple"?
emergency
Before the plural surname, it means a family or couple
The whites came to see me yesterday
whole family
The family
Fine
Both are OK. You can judge by context.
It must be a family~~
The Wangs are the Wangs.
It depends on context
All right
It's possible. It depends on the context
whole family
When "each" is an appositive, do you use "each" when the noun or pronoun is singular or plural
You can't use plural after each!
Give the function examples f (a + b) = f (a) f (b) f (AB) = f (a) f (b)
f(a+b)=f(a)f(b) f(x)=2^x
f(ab)=f(a)f(b) f(x)=x
In English, if two coordinate uncountable nouns are used as subjects, whether the predicate verb is singular or plural, and if the pronoun is used instead of them, whether they are it
In the plural
For any AB belonging to R, the function FX has f (a + b) = f (a) + F (b) - 1, and when x > 0, f (x) > 1, the increasing function FX is proved
If f (4) = 5, solve the inequality f (log2 (2x-1)
Because f (0) = f (0 + 0) = f (0) + F (0) - 1, f (0) = 1. Because f (0) = f (x-x) = f (x) + F (- x) - 1, f (- x) = 2-F (x) let a > b, then f (a-b) = f (a) + F (- b) - 1 = f (a) + 2-F (b) - 1 = f (a) - f (b) + 1. Because A-B > 0, f (a-b) > 1. Therefore, f (a-b) = f (a) - (b) + 1 > 1, that is, f (a) - f (b) > 0
Do the verbs after each of + nouns use the singular or the plural?
Each of + noun plural as the subject, after the predicate verb with the singular, because each is the subject
singular
singular
Give an example of a function satisfying f (AB) = f (a) + F (b)
Logarithmic function is OK
For example, log24 = log22 + log22
This is the functional equation of logarithmic function.
For example, f (x) = LNX
y=lgx
The logarithm function is satisfied
Each of us has a memory.each Of them has a head like this. What forms of verbs follow the accusative us, them and plural nouns
Because each doesn't have a meaning, the verb needs to add s
But when each is placed after the subject, there is no need to add
eg They each have a cup.
Each means each, so it's a simple three
Each is emphasized here,. So use the singular
Let f (x) defined on R satisfy f (x) times f (x + 2) = 13, if f (0) = 2, find f (2010)
f(x)=13/f(x+2)
Using X + 2 to replace x
f(x+2)=13/f(x+4)
Substituting the above formula
f(x)=13/（13/f(x+4)）=f(x+4)
So the period of the original function is 4
f(2010)=f(2)
From F (x) × f (x + 2) = 13
So f (0) × f (2) = 13
f(2)=13/2=f(2010)
F (x) = x 1 = (x 1 / 2) 3 / 4 when x
F (0) * f (2) = 13, so f (2) = 6.5, f (4) = 2, f (5) = 6.5
So the odd times of 2 is 6.5, and the even times of 2 is 2. 2010 is the even times of 2, so f (2010) = 2
