Question

x f(x)-2 -6-1-10 212 23-14 -6Which interval could contain a solution to f(x) = 0?A. -6

Answer 1

Notice that when x = -1, f(x) = -1, and if x = 0, then f(x) = 2.

As we can see, the values of f(x) change from negative to positive between -1 and 0. This means that between the interval -1 < x < 0, we can find f(x) = 0
