If you know your square roots, you know the number should be between 4 and 5 because 4^2 is 16 and 5^2 is 25. The answer is 4.4721 but rounded it should be 4.5 because the 7 is more than 5 and it should be rounded up.

Answer:

f(x) = (x + 10)(x + 4)(x - 1)

Step-by-step explanation:

Given the zeros of a polynomial, say x = a and x = b, then

the factors are (x - a) and (x - b)

The polynomial is then the product of the factors

f(x) = (x - a)(x - b)

Here the zeros are x = - 10, x = - 4 and x = 1, thus the factors are

(x - (- 10)), (x - (- 4)) and (x - 1), that is

(x + 10), (x + 4) and (x - 1)

f(x) = (x + 10)(x + 4)(x - 1)
