can someone help me with this question is super confusing.
cube with side length x has been modified by adjusting its side length x has been modified by adjusting its length, width and height. A student determined a function of the form v(x)=(x+a)(x+b)(x+c) can be used to represent the volume of the new box for different values of x, and then she graphed the function.
a.based on the graph ,predict how the side lengths of the original cube changed.(hint:what do the zeros of the function represent?
b.determine a polynomial function of the form v(x)=(x+a)(x+b)(x+c) that's matches the function in the graph .
c.which parts of the graph are realistic?(hint:all sides must be positive.using two negative side lengths to give positive volume is not realistic.)
