Question

Consider the function 4(x)=√5x-5+1 Which inequality is used to find the domain?

A: 5X-4>0
B: √5x-5+1>0
C: 5x>0
D: 5x-5>0

Answer 1

`5x-5\geq 0`

Explanation:

We are given

`f(x)=√(5x-5) +1`

Domain:

we know that domain is all possible values of x for which any function is defined

We know that value inside sqrt should always be positive

so, value inside sqrt is 5x-5

so, we get

`5x-5\geq 0`
