Which is a valid prediction about the continuous function f(x)? f(x) ≥ 0 over the interval [5, [infinity]). f(x) ≤ 0 over the interval [–1, [infinity]). f(x) > 0 over the interval (–[infinity], 1). f(x) < 0 over the interval (–[infinity]. –1).

The answer is ""

Explanation:

In this question, the first choice is correct because it is hard to say without seeing the charts we wouldn't understand the rule feature, it could be said the very same. Even so, three non-responses may be omitted.  

In choice B, it is incorrect since f(x) has an [1,3] interval, in which it shows below zero, but f(x) is not below zero for the residual period to the left of x+3.   In choice C, it is wrong because the x = -1 value contributes to f(x) = 0, which may never exceed 0.    In choice C, it is wrong because it gives the 8 and 4, which was positive.
