Which is the graph of f(x) = (x - 1)(x + 4)?

You can determine this by finding zeros of quadratic function,

.

Which eliminates first and third option.

Now we have up and down parabolas left.

If we factor we find that the coefficient before determines how it is turned, since its positive its an upward turned parabola hence the answer is the last graph.

Hope this helps.
