Write a quadratic function in the standard form who's graph satisfies the given conditions

1. Passes through (-5,0), (1,0), and (4,0)

This is frankly impossible.

Step-by-step explanation:

What you have given me are three x-intercepts. And it is impossible for a quadratic function to have more than two roots. However, if this was an cubic function, we could multiply (x+5) (x-1) (x-4) which results in the equation which simplifies into x^3 - 21x + 20. However, this is a cubic function, not a quadratic function, so something must be wrong with this problem all together.
