Answer:
x = -4 is not in the domain of the function f(x)
Explanation:
To find the domain of the function f(x) = (x - 7) / (x + 4), we need to identify any values of x that would make the denominator of the fraction equal to zero, since division by zero is undefined.
Setting the denominator equal to zero and solving for x, we get:
x + 4 = 0
x = -4
Therefore, x = -4 is not in the domain of the function f(x), the domain of the function f(x) is all real numbers except x = -4, since all other values of x will produce a defined output for the function.
