The graph of the polynomial f(x)=(x−3)(2x+5)(x−1)(x+4) has x-intercepts at 4 different values. List the values:

Answer 1

The x intercepts are where f(x) = 0. In this case, the x values are arrived at by making any of the parenthetical terms = 0. I'll do the most complicated one and leave the rest for you:

2x + 5 = 0 x = -5/2
