What is the range of the function ${\displaystyle y=x^2}$?

The domain and range of $y=\sin <!--\; \; -->x$ is
A)$R,[0,\mathrm{\infty <!--\; \infty \; -->}]$
B)$R,[-<!--\; -\; -->1,1]$
C)$R,[-<!--\; -\; -->\mathrm{\infty <!--\; \infty \; -->},\mathrm{\infty <!--\; \infty \; -->}]$
D)$R,[1,\mathrm{\infty <!--\; \infty \; -->}]$

Mean of the squares of the deviations from mean is called the:
Variance
Standard deviation
Quartile deviation
Mode

What is the range of the function y = x?

Tell whether the statement is true or false : A data always has a mode.

In most cases,_____variables are not considered to be equal unless they are exactly the same.

A local newspaper in a large city wants to assess support for the construction of a highway bypass around the central business district to reduce downtown traffic. They survey a random sample of 1152 residents and find that 543 of them support the bypass. Construct and interpret a 95% confidence interval to estimate the proportion of residents who support construction of the bypass.

$3+3x3-3+3=?$What is the right answer and how?

Define lateral displacement.

What is the simplified form of the following expression assuming all variables are non-zero values? $\frac{(X\times <!--\; \times \; -->Y)}{X}\times <!--\; \times \; -->\frac{Z}{Y}=$

We need to determine whether the variable is qualitative or quantitative. The mpg a car gets while driving on the highway Is the variable qualitative or quantitative?

Which statement best describes the domain and range of $f(x)=-<!--\; -\; -->(7{)}^X$ and $g(x)=7^X$ ?

When is graph G with n vertices is isomorphic to complement $\stackrel{¯<!--\; ¯\; -->}{G}$?
Question : When is graph G with n vertices is isomorphic to complement $\stackrel{¯<!--\; ¯\; -->}{G}$?
So, total no of edges that a n vertex graph can have is $(\genfrac{}{}{0ex}{}{n}{2})$. And if G is isomorphic to $\stackrel{¯<!--\; ¯\; -->}{G}$ then no of edges in G is equal to no of edges in $\stackrel{¯<!--\; ¯\; -->}{G}$. So no of edges in $(\genfrac{}{}{0ex}{}{n}{2})$ . But for this to be an integer, n = 4k or n = 4k+1 for some integer k.
My question is : Is this the only requirement? That is, is n=4k or 4k+1 the sufficient condition to construct such a graph G? Does it have anything to do with the fact that G and $\stackrel{¯<!--\; ¯\; -->}{G}$ can both be bipartite if both of them don't have any triangle in it? The question asks to think about what is the condition of G and $\stackrel{¯<!--\; ¯\; -->}{G}$ simultaneously bipartite.
