Question

Which of the following describes the polynomial function?

Answer 1

Your image is cropped, so I can’t see the options to choose from but this would work too:

=> (x-2)(x-5)(x-7)
=> (x^2 -5x -2x +10)(x-7)
=> (x^2 -7x +10)(x-7)
=> (x^3 -21x^2 +10x -7x^2 + 49x -70)

=> x^3 -28x^2 + 59x -70

The following is true:

* the polynomial has a positive leading coefficient.

* the polynomial has a domain of x = (-oo, oo)
