Question

Find the domain of f(x). give your answer in interval notation.

a) (-[infinity], [infinity])
b) [0, [infinity])
c) (-[infinity], 0] U (0, [infinity])
d) None of the above

Answer 1

The domain of the function f(x) is [0, 20].

Step-by-step explanation:

The domain of the function f(x) is the set of all possible values of x for which the function is defined. In this case, the function f(x) is a horizontal line for 0 ≤ x ≤ 20, which means that f(x) is defined for all real numbers between 0 and 20, inclusive.

Therefore, the domain of f(x) is [0, 20] in interval notation.
