Question

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

Answer 1

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
