Question

Which of the following are roots of the polynomial function? (check all that apply)

f(x)=x^3-7x^2+13x-6

Answer 1

the answers is b,d, and f

Explanation:

Answer 2

B, D and F

Explanation:

Roots are the x intercepts of a curve i.e the points where the curve crosses or touches the x axis. Since these are always on the x axis, the y coordinates of these points are always 0. So to find the answer here, you substitute each possible answer into the function and it if it gives you y=0 then you know that it is a root. (2,0) being the first example.
