If f (x) = sqrt4x + 9+2 which inequality can be used to find the domain of f (x)

The inequality would be 4x + 9 ≥ 0

Step-by-step explanation:

You could use this inequality to solve the domain as any number can be put into this equation as long as it doesn't make what is under the square root symbol (4x + 9) negative. Therefore, you can build this inequality and solve from there if you would like.
