Question

Select the interval where f(x) > 0.

a) -2 < x < -1
b) 1 < x < 2
c) 4 < x < 5
d) Negative infinity < x < Positive infinity

Answer 1

The interval where f(x) > 0 is 0 ≤ x ≤ 20.

Step-by-step explanation:

To determine the interval where f(x) > 0, we need to examine the graph of the function f(x). Since the graph of f(x) is a horizontal line and 0 ≤ x ≤ 20, we know that f(x) is positive for all values of x within that range. Therefore, the interval where f(x) > 0 is 0 ≤ x ≤ 20.
