Answer: e. x≠2 f. x≥-1/2

Explanation:

Domain is basically the x value of a function.

----------------------------------------------------------------

Question e.

g(x)=5/(2-x)

First, keep in mind, the denominator of a fraction can not be zero or else it will be undefined.

Since x is in the denominator: 2-x≠0

2-x≠0

x≠2 Yes, this is the domain

----------------------------------------------------------------

Question f

h(x)=√(2x+1)

For a standard square root, the value inside can't b negative

So 2x+1≥0

2x≥-1

x≥-1/2 Yes, this is the domain

Hope this helps!! :)

Please let me know if you have any question
