Question

I need help with B find the roots

Answer 1

-1 and 3

Explanation:

The roots of the quadratic function can be determined by
`f(x')=0` where x' is the roots of the quadratic function. In that graph, x = -1 and x = 3 makes the value of f(-1) = 0 and f(3) = 0. So, x = -1 and x = 3 are the roots of the f(x).
