Question

Which of the following represents the factorization of the polynomial function graphed below? (Assume it has no constant factor.)

Answer 1

OPTION C: y = (x -1)(x - 5)

Explanation:

Note that the graph cuts the x - axis at x = 1 and x = 5.

This means the zeros of the polynomial are at x = 1, 5.

Therefore, the equation would be: y = (x -1)(x - 5).

Substituting x =1 or 5 would render the polynomial zero.

So, we say that the above equation is the solution.
