For this case we have a function of the form: y = f (x) Where, x: independent variable y: dependent variable To answer the question, we must see in the table the values of the independent variable x, for which the values of the dependent variable f (x) are negative. We then have that the interval that satisfies this condition is from minus infinity to less than 4, not including 4. Therefore, (–∞, -4) Answer: The interval on which the function f(x), is negative: D) (–∞, -4)
