Which polynomial function has a leading coefficient of 1, roots –2 and 7 with multiplicity 1, and root 5 with multiplicity 2? f(x) = 2(x 7)(x 5)(x – 2) f(x) = 2(x – 7)(x – 5)(x 2) f(x) = (x 7)(x 5)(x 5)(x – 2) f(x) = (x – 7)(x – 5)(x – 5)(x 2)

The polynomial function we can actually see that has a leading coefficient of 1, roots –2 and 7 with multiplicity 1, and root 5 with multiplicity 2 is: f(x) = (x – 7)(x – 5)(x – 5)(x + 2).
What is polynomial function?
Polynomial function actually refers to the function that has only non-negative integer powers. Also, it can also be a function with positive integer exponents only.
Thus, f(x) = (x – 7)(x – 5)(x – 5)(x + 2) is the correct polynomial function.
