PLEASE ASAP WILL MARK BRAINLIEST f(x)=(x+4)(x−2)(x−1) has zeros at x=−4, x=1, and x=2. What is the sign of f on the interval -4 is less than x is less than 1

Applying a numeric value to the function on the interval, it is found that f is positive on the interval -4 < x < 1.

The function f is given by:

On the interval -4 < x < 1, to find the sign, we find the numeric value for a value of x, which we are going to use x = 0.

Hence:

Hence, f is positive on the interval -4 < x < 1.
