For real number a, which of the following equations are true ? Select all that apply.
trapecia [35]

ANSWER

\lim_{x \to \: a}(x)  = a

\lim_{x \to \: a}(a)  = a

\lim_{x \to \: 5}(x)  = 5

EXPLANATION

For real number 'a',

\lim_{x \to \: a}(x)  = a

is true because we have to plug in 'a' for x.

\lim_{x \to \: a}(a)  = a

This is also true because limit of a constant is the constant.

\lim_{x \to \: 5}(4)  = 5

is false. The correct value is

\lim_{x \to \: 5}(4)  =4

\lim_{x \to \: 5}(x)  = 5

is also true because we have to substitute 5 for x.

\lim_{x \to \: a}(a)  = x

is also false

The limit should be

\lim_{x \to \: a}(a)  = a
