Question

If f (x) = √4x + 9 + 2, which inequality can be used to find the domain of f(x)? a. √4x ≥ 0 b. 4x + 9 ≥ 0 c. 4x ≥ 0 d. √4x + 9 + 2 ≥ 0

Answer 1

The correct inequality to find the domain of f(x) = √(4x + 9 + 2) is a. √(4x) ≥ 0.

Step-by-step explanation:

To find the domain of the function f(x) = √(4x + 9 + 2), we need to determine the values of x for which the function is defined.

Since the square root function is only defined for non-negative values, we can set the expression inside the square root greater than or equal to zero.

From the given options, the correct inequality to find the domain of f(x) is a. √(4x) ≥ 0.
