Question

What is the domain of the equation y=1/X+5?

Answer 1

Domain is

{

x

∈

R

;

x

≠

−

5

}

Range is

{

y

∈

R

;

y

≠

0

}

Explanation:

Explanation:

Domain: Denominator should not be

0

∴

x

+

5

≠

0

or

x

≠

−

5

Domain is any real value except

x

=

−

5

or

{

x

∈

R

;

x

≠

−

5

}

Range is any real value except

y

=

0

or

{

y

∈

R

;

y

≠

0

}
