Apolynomial function has roots –5 and 1. which of the following could represent this function? f(x) = (x + 5)(x + 1) f(x) = (x – 5)(x – 1) f(x) = (x – 5)(x + 1) f(x) = (x + 5)(x – 1)

f(x) = (x + 5)(x - 1)

using the ' factor theorem '

given x = a is the root of a polynomial then (x - a ) is a factor

here roots are x = - 5 and x = 1 hence factors are (x + 5) and (x - 1)

the polynomial is the product of the factors

f(x) = (x + 5)(x - 1)

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
