Determine the domain of the function.

f as a function of x is equal to the square root of x plus one divided by x plus four times x minus six.

x ≥ - 1, x ≠ 6

All real numbers except - 4 and 6

All real numbers

x ≥ 0

We are given with a verbal phrase of a function of x is equal to the square root of x plus one divided by x plus four times x minus six.

This is expressed as f (x) = √ (x) + 1/x + 4x - 6

the domain are values which include only natural numbers because of the square root sign. answer is D. x ≥ 0
