Most of the + countable noun is plural. Is the whole subject singular or plural? Most of the + countable noun is plural. Is the whole subject singular or plural?

Most of the + countable noun is plural. Is the whole subject singular or plural? Most of the + countable noun is plural. Is the whole subject singular or plural?

It depends on the number of nouns followed and whether they are countable to determine whether the predicate is singular or plural!

The Smiths is the subject verb singular or plural
The Smiths means the Smiths
The Smiths means the Smiths
The Smiths have three children.
The Smiths have three children.
The Smiths were living in peace with the neighbors.
The Smiths live in harmony with their neighbors.
The Smiths occupy the house on the corner.
The Smiths live in the house around the corner.
The Smiths is the subject and the verb is plural
Is the number of followed by a countable noun or an uncountable noun
A countable noun can be added after the number of
I think the number of is followed by a countable noun because it means "what is the number of"
the number of people or thenumber of apples
It can add anything, as long as it is the quantity of one thing, but the number of sth. should be in the form of is. ha-ha
The number of boys is very large.
"The number of" is followed by the plural of countable nouns. When the whole is the subject, the verb be is singular.
Add a countable noun, the number of is to describe the number, after can't add uncountable.
The number of can be followed by a countable noun or an uncountable noun. The difference lies in the singular and plural forms of the be verb after it
the number of rooms
The known points a (- 2, Y1), B (- 1, Y2), C (4, Y3) are all on the image of inverse scale function y = - k2-2 / X
Size relation of Y1, Y2 and Y3 (from large to small) (writing process)
First, let's look at the function y = - 2 / X （1）
Function y = - k2-2 / X （2)
Function (2) is based on function (1) left and right translation to get the approximate image of function (2)
So, we can observe the function image, Y1 > 0, Y2 > 0, y3y1, so we can get
The answer is yes
How to judge whether a periodic function is a periodic function?
For example, how to judge whether y = sin | x | is a periodic function?
If the function is periodic and the period is t (T > 0), then f (x) = f (x + T) sin | x + T | = sin | x | when - T
On the logarithmic function. The logarithmic function with 2 as the base and P-X ^ 2-2x as the true number has no zero point in the domain of definition, so the range of P can be obtained
You don't have to work it out
If there is no zero point
Then P-X ^ 2-2x is constant greater than 1 or constant greater than 0 is less than 1
p-x^2-2x＝p+1-（1+x）^2
Because - (1 + x) ^ 2 is always less than 0
P + 1 - (1 + x) ^ 2 is always less than P + 1
So 0 < p + 1
If there are three points (- 1, Y1), (- 1 / 4, Y2), (1 / 2, Y3) on the image of the function y = - A & sup2; - 1 / X (a is a constant), then the size of Y1, Y2, Y3 of the function
Idea: to do this problem, the first thought is to draw a picture, a unknown can be replaced by some special values, I used 1. The result shows that the function is increasing from - 1 to real infinity. When the current half is different, we can discuss it. There are three cases (1) when a belongs to negative infinity to - 1 and 1 to positive infinity: Y1 < Y2 < Y3 (best
How to judge a function as a periodic function
There exists any a, B ∈ R, and a, B are not 0 at the same time
bring
f(x + a) = f(x+b)
It is true for any x constant in the domain
Then f (x) is a periodic function
If there exists t such that f (x) = f (x + T), then the period of this function is t
See if he has cycles
In logarithmic function, base number has definition field, logarithm and true number have? What is it
True number must be greater than zero logarithm any real number can be
If M (- 1 / 2, Y1), n (- 1 / 4, Y2), P (1 / 2, Y3) are all in the function y = KX + B (k)
∵ky2>y3
