Question

h(x)=x-4 What is the domain of h ? Choose 1 answer: A All real values of x such that x!=4 (B) All real values of x such that x>=4 (C) All real values of x such that x!=5 (D) All real values of x su

Answer 1

The domain of the function h(x) = x - 4 is all real numbers, as subtracting 4 from any real number is valid. Therefore, the correct choice is (A) All real values of x.

Step-by-step explanation:

The domain of a function is the set of all possible input values (typically x values) for which the function is defined. For the function h(x)=x-4, there are no restrictions on the values that x can take, since subtracting 4 from a real number always results in another real number. Therefore, the domain of h is all real numbers.

To express this more formally, we state that the domain of h is x is a real number. In terms of the options provided, answer (A) All real values of x is correct as it does not impose any unnecessary restrictions on the value of x.

Answer 2

The domain of h(x) = x - 4 is all real values of x.

Step-by-step explanation:

The function h(x) is defined as h(x) = x - 4. The domain of a function is the set of all possible x-values for which the function is defined. Since h(x) is defined for all real numbers, the domain of h is all real values of x.
