Question

Which function has two x-intercepts, one at (0, 0) and one at (4, 0)? f(x) = x(x − 4) f(x) = x(x + 4) f(x) = (x − 4)(x − 4) f(x) = (x + 4)(x + 4)

Answer 1

Answer:

The answer is D on edge

Step-by-step explanation:

Answer 2

If you want a polynomial to have the x-intercepts of your choice, you simply have to build a polynomial by multiplying pieces like $(x-x_k)$ where $x_k$ is the x-intercept you want.

So, if you want x-intercepts 0 and 4, you have to build the polynomial

$(x-0)(x-4) = x(x-4)$
