Answer:

The third choice.

Step-by-step explanation:

This is a linear function.

The equation is y = (x - 5)(5x + 4) - 5x^2.

y = 5x^2 - 25x + 4x - 20 - 5x^2

y = 5x^2 - 5x^2 - 21x - 20

y = -21x - 20

That means this is a linear function, with a linear term of -21x and constant term of -20.

Hope this helps!
